games i liked in 2023 (And Other)
I like games ! You know that ?! and I played a lot 2023! and I liked a lot :). They aren't in any specific order, it's just a little highlight of games that stood out to me this year. I've attempted to write a few thoughts on each so I hope take a look. I wrote playtimes for some also but that is very subjective.
-Ones that actually came out 2023-
Lunacid https://store.steampowered.com/app/1745510/Lunacid/ I think I mentioned enjoying this in 2022 but it officially released so I can say it was one of my favorite games in 2023 :3! I like to feel around this game's walls for secrets. I like the npcs that are full of hope and whimsy despite the bleakness of its world. Chill and occasionally spooky first person dungeon crawling around moody caverns and ruins varying from underground forests to vampire castles and blood lake. (Blood lake!!!! Lake of blood!!! Big creature there.) Lots of fun weapons and spells to find, I like the one that lets you turn blood into coffins.

~20 hours
Orbo's Odyssey https://feverdreamjohnny.itch.io/orbos-odyssey If you played the massively popular demo for "Peeb Adventures" by feverdreamjohnny then you know that Johnny makes some fun and funny games and this is certainly one of them. speedy and satisfying platforming! funny dracula moments! short and sweet.
Tumblr media
~2 hours
A Walk in the Woods https://mooncaller.itch.io/a-walk-in-the-woods Quaint little GBStudio game :) Made by some friends of mine for a jam :) It's cute I like it. There's minigames where you catch bugs and birdwatch.
Tumblr media
~30 minutes long
Undertale Yellow https://gamejolt.com/games/UndertaleYellow/136925 I've only completed the pacifist run and checked out a neutral run so far. as the title somewhat implies, this is a prequel to Undertale where you play as the fallen human who had the yellow colored soul. This Undertale fangame has a lot of charm!!! A lot of battles really feel like they could have been in the original, with quite a bit of extra flair in some circumstances.
Tumblr media
~10 hours
vs really cool bird https://bobacupcake.itch.io/vs-really-cool-bird you know that really cool bird that rob bobacupcake made well you can fight it in undertale and it's really fun. yeah two undertale fangames. . . wat of it …
Tumblr media
~30 minutes
Misericorde: Volume One https://xeecee.itch.io/misericorde I wont lie the main draw for me into this was cute anime nuns I sure didn't know a whole lot else about it when I dug into it. But it's (the first part of) a VN murder mystery! And I enjoyed it a whole lot. All the characters are memorable and I really enjoy how all of them have differentiating designs. The protagonist is so failgirl. She sucks so much and I love her. I'm very intrigued by the mechanics of the game's world, it clues you in near the beginning to expect something a bit supernatural/fantastical, which gives you (and later the protagonist) a curiosity about what's real and what isn't. The music is all very impressive too, with the ost reaching past 100 tracks varying through post-rock, folk, drum & bass, and others. (Remembering when the track "Scandal" played and my friends and I took a moment to be like- okay hang on this track pwns.) Big fan of its haunting locals and how the aesthetic of the game fits them well. Also the humor is a lot of fun, and I love all the moments getting to know the different characters. Very excited to see the eventual continuation of this.
Tumblr media
~12 hours
Absolutely Perfect Specimen https://chambersoft.itch.io/absolutely-perfect-specimen It seems like a lot of people are craving toxic horror yuri lately. Here's a recommendation. It's a VN about the android maid "Pan" and the mad scientist girl who created her. Horrifying & gut wrenching & largely about having other people define you. The art and music is haunting & poignant and matches the ever increasing feeling of dread throughout. It's yuri with the chunks. Peak robotgirl horror for those who can stomach it.
Tumblr media
~90 minutes
Wordhopper https://kokoscript.itch.io/wordhopper Very quaint word search type puzzle game for ms dos! I think its style is very slick and that's pretty impressive to see. Chill game with nice vibes and eyecandy visuals. also it was so cool to have played this and then ended up seeing the dev's booth at Vintage Computer Festival Midwest. I was like omg woah I just played this.
Tumblr media
~bunny
Bossgame https://lilyv.itch.io/bossgame This game is yuriful as f*ck. Delightful humor and fun character dynamics! A simple-to-understand-difficult-to-master boss rush battle system that makes you satisfied to get it right, and enticing to get just a little farther if you get it wrong. There's a lot of detail and charm to this game's menus and dialogues and win screens, I remember noticing that once you beat a boss there would be some marquee text that would pass by with some prose on it. I love how it balances its silly moments with its heartfelt moments and its high octane moments. I like the character development and revelations had throughout the plot. & I like how good the protagonists are for each other :) It's very sweet. It's hype as hell. if you want some boss rush action paired well with that sweet sweet girl's love, you *will* play this game.
Tumblr media
~5 hours
Elly's Adventure https://bikwins.itch.io/ellys-adventure Very cute and witchy!! You are the little witch girl "Elly" on an adventure to get your toys back!! Feels like a pretty authentic gameboy type experience, it takes a lot of design cues from Kirby's adventure and the like. I am a big fan of how playful it feels.
Tumblr media
~1 hour
Nour https://store.steampowered.com/app/1141050/Nour_Play_with_Your_Food/ This was a treat for me, but I understand that not everybody is going to get it. It's a game where you play with food(and food accessories). And that's it. It knows what it was going for. I think a lot of people were expecting something else for some reason. It's a cute little toy game and I felt satisfied with my time with it.
Tumblr media
~food
Hi-Fi Rush https://store.steampowered.com/app/1817230/HiFi_RUSH/ Do I have to say this game is super fun? It's a big one everybody probably already knows it. This game's dopey humor made me laugh a lot and I'm not afraid to admit it.
Tumblr media
~12 hours
WHISKEY.ST2007S https://bonicle.itch.io/whiskey-st2007nes One of the last games I played in the year because it released super last minute. Does anybody else get a rush when running a shopping cart down the parking lot? This emulates that feeling. Short game where you collect whisky stones in the whisky stone dimension because you forgot to go christmas shopping until the very last minute. it rules. It's very short you can go play it right now & get a highscore.
Tumblr media
~5 minutes
re:curse https://devpalmer.itch.io/re-curse Discovered this one near the very end of the year also. Fun little rpg maker horror/humor game about a weird scientist lady, her butch, and an evil clown computer virus that figured out how to warp reality. I got a kick out of it. and also enjoyed digging through the game's files, which was actively encouraged by the dev, which I thought was very fun.
Tumblr media
~90 minutes
-Didn't technically get to until 2024 but released last year-
SWOLLEN TO BURSTING UNTIL I AM DISAPPEARING ON PURPOSE https://1207.itch.io/swollen-to-bursting-until-i-am-disappearing-on-purpose People love to dunk on a lot of indie rpgs for being "quirky Earthbound inspired and about depression" or whatever. Earthbound's great. If people can nail the kind of humor and absurdity it likes to pull off while also balancing difficult topics I think that deserves a high mark. SWOLLEN TO BURSTING was fun. Bizarre and charming places to explore & distressing secrets to find. I like how it blends meander-around-the-town gameplay with Yume Nikki sort of exploration and effects. Also I'm a big fan of the music. I like how it has the lofi sound which matches the early 3d look of the game.
Tumblr media
~6 hours
HalOPE https://starbage.itch.io/halope Another for the fans of sweet little rpg maker games that have a lot of heart. HalOPE is about an incomplete little angel wondering through worlds. Each has a theme, usually to do with an emotion or feeling, and they do well at evoking that feeling as well as its antithesis. a lot of the music is very homey and charming at moments and unnerving at others, sometimes lonely, all doing well in their corresponding chapters to further the feeling of its specified theme. There are so many delightful characters and designs in this & I found myself feeling really attached to their tiny little stories. The narrative at the core of it all hit me. If I may be vulnerable, I cried a whole lot at various moments in this game. It was really cathartic. I feel very excited for people to experience this game.
Tumblr media
~5 hours
-Favs I finally got around to that didn't come out 2023-
An Outcry https://quinnk.itch.io/an-outcry Kind of sad it took me so long to get to this one, but glad it meant I got to play the "definitive" updated version of it. Apartment wandering RPG maker horror. Bum smokes from your neighbors and use them to save the game. I wish I could unwrap a lot more of what I like about this game than I can without spoiling too much. But if I could, I'd probably go on for too long. Let me attempt to be succinct & not giving too much away. You can tell pretty early on that An Outcry is about taking action when necessary & not turning a blind eye. What it explores about player vs protagonist agency is very fascinating to me as well, and I enjoyed learning about the inspirations for why the game's narrative works the way it does. The character Anne is such a sweetie and I love her a whole lot. This game has a very tangible feeling, this apartment complex is dirty and crumby, it smells of smoke, and there's a surrounding desperation you can feel.
Tumblr media
~5 hours
Pigments https://punkcake.itch.io/pigments Honestly I had gotten this game in a bundle and while I was playing it I hadn't looked at the name and I just kept calling it FRUIT. On call with my friends I'd be like "hey im gonna play more FRUIT". I straight up didn't read the title screen. But it's called Pigments. You play as a fruit and you try to paint the whole floor and not get sliced by buzzsaws. Fun little arcade type game.
Tumblr media

Bridge, October 3rd https://lowpolis.itch.io/bridge-october-3rd Very short vignette. I like it. It's what it says it is. I'm not going to overexplain.
Tumblr media
~like a minute
-Other Games I Want To Mention-
Pseudoregalia https://store.steampowered.com/app/2365810/Pseudoregalia/ I think a lot of people might have already known this one but I felt like it was a pretty fun 3d platformer. There were a few issues I had with it (boss fight at the beginning was frustrating, and I got lost a lot [but it looks like there's been a map patch by now, so, perhaps for some that is a fix]). I enjoyed it but sure felt weird that the only accessibility option was to give the protagonist pants. What kind of joke is that?
Tumblr media
~5 hours
Mushroom Musume https://mortallymoonstruckgames.itch.io/mushroom-musume (Disclaimer, this game is still early access, but I saw a lot of people talking about it last year. SO I will mention here?) Haven't played much of this yet, but I have enjoyed what I played so far!! As of writing I've gone through 6 playthroughs, I feel like I've hardly scratched the surface and I've been so impressed by its depth. It's very charming, you never know what sorts of fairytale shenanigans are going to happen, and it's very cool to see how your different stats will affect things. It very much plays out like a roguelike vn. Which is not the sort of thing you may expect to make much sense but it pulls this off well. Also all the mushroom girls are very cute and I love them very much. I hope the sad goopy one who had bugs in her skin rests in peace.
Tumblr media
~mushroom
Knuckle Sandwich https://andybrophy.itch.io/knuckle-sandwich -_- Hm. Where do I start with this one. I was pretty excited for this one since the demo and kickstarter in 2018. I felt like the demo was a hell of a hook that got me curious & horrified. As time went on, it seemed to be shaping up into something really cool. turn based combat with action commands and wario-ware-type microgames?? with a banging soundtrack?? like, count me in!! Then it released and well, the gameplay, art, music all delivered. It was very fun and engaging in those aspects. But the story… oh it just devolves into disappointing nonsensical randomness. The whole hook at the beginning seemed to be completely thrown away for the wild goose chase plot that ensues, leaving you to wonder if it was ever going to be relevant again. It felt like it had no idea what it was trying to say or do. It disappointed me that a game that has so much good in so much else about it gets brought down so much for me by this plot.
Tumblr media
~12 hours
Rhythm Doctor https://store.steampowered.com/app/774181/Rhythm_Doctor/ (Putting this one in mentions because it is early access.) I really enjoyed the act 5 release. When I first saw this game, I kind of shrugged it off, thinking "that base mechanic doesn't seem like it will last". I thought it was basically just that one ghost shooting game from Rhythm Heaven which I Hate. Well let's just say I am now seeking penitence for my previous transgressions. It's really fun. There's a lot more to it that I didn't know when I first took a look. Also, consistently amazed by people's custom levels, I had no idea that its level editor allows people to do so much in it, I look at some levels and think "This editor seems as complex as an industry standard video editor". I'm looking forward to what they're planning next, very curious how they could possibly one-up the last update.
Tumblr media
~rhythm
El Paso Elsewhere https://strangescaffold.itch.io/el-paso-elsewhere This was really fun & funny so far but unfortunately I had been encountering an issue with a certain level where the game would crash. I reported the issue, got a response, and there has been an update since then so I think there's a possibility that it got fixed but I have not tried yet. I would like to return to this sometime but having to relearn controls midway through is always daunting to me.

-Things that looked good but didn't get around to-
Cosmic Wheel Sisterhood https://store.steampowered.com/app/1340480/The_Cosmic_Wheel_Sisterhood/ Still don't know a whole lot about this. But there are witches, and I like witches.
Casette Beasts https://store.steampowered.com/app/1321440/Cassette_Beasts/ I haven't felt thrilled about Pokémon lately. I know a lot of people seemed to really enjoy this little monster-collecting-rpg. The style is appealing to me as a die-hard gen 5 fan. I started playing it but haven't set aside the dedicated time for it yet, but I'm excited to dig in more when I do.
Little Goody Two Shoes https://store.steampowered.com/app/1812370/Little_Goody_Two_Shoes/ Started watching a friend play this, and I'm certainly curious.. Some sort of horror fairytale but also there's yuri? Yum. Enjoyed the style and animation in the nightmare segments that I saw.
Venba https://store.steampowered.com/app/1491670/Venba/ I've picked this up a while ago but still haven't gotten around to it, but I'm eager to, I've heard nothing but good things.
Goodbye Volcano High https://store.steampowered.com/app/1310330/Goodbye_Volcano_High/ I think there are gay dinosaurs in a band and it's going to be the apocalypse? I have also heard nothing but good things about this.
-Things I watched friends play-
Signalis https://store.steampowered.com/app/1262350/SIGNALIS/ This was a pretty big one. You probably already know it, right? Watched a friend play this and I missed various parts but I understood a solid bit of it. hey. robotgirls are always getting put in these fucked up situations. have you noticed this? one time i got really high and cried about it. it isn't fair
Bomb Rush Cyberfunk https://store.steampowered.com/app/1353230/Bomb_Rush_Cyberfunk/ This one was also probably big enough you don't need me to sing its praises. but it looked really neat. swag.
-Various Thoughts-
Lately I've been thinking more about design and narrative. I feel like I haven't been doing as much analysis as I should be when it comes to games. I want to dissect more what games are saying and figure out meaning. Also attempt to see how the mechanics aid in that. I feel like most of my own work is pretty abstract & random. I simply make what I like. While that's fun and all, I still want to improve in a lot of ways, especially in having more of a theme or message. Figuring out how other games accomplish this is obviously a good step toward this.
If you saw games here that interest you I highly urge you to take a look, many are pretty short, and I pretty explicitly wanted to highlight some smaller titles. If you know me you know I like to uplift small games. (Save for the occasional big game, but that's rare these days) I think it's healthy for you to play and support independently developed & published works. I don't want to ramble too much this time about why that's important, but I hope that you might have found something you may enjoy here and if not then I encourage you to find small stuff that you would like. And I would like to encourage everybody to share their findings as well! Little games need our help to be seen and talked about! They don't have the budgets the big ones do for advertising, and advertising on your own is a whole ton of work. If you like something, spread the word! I'm sure the developers would very much appreciate that.

An SVP abstract teases the presence of reddish or yellowish pigments in Diplodocus hinting at a wider color palate in sauropods than what we usually depict them with. This reminded me that we went quite experimental with our Europasaurus design back then and it doesn't seem that unlikely now anymore.

Harvard University has a library that protects the rarest colors in the world.
The Straus Center for Conservation and Technical Studies houses the Forbes Pigment Collection, which contains more than 2,500 samples of pigments, some incredibly rare and harvested from things like mummies, heavy metals, poisons, and precious minerals.
The collection was amassed by Edward Waldo Forbes (1873-1969), who directed Harvard's Fogg Museum, between 1910 and 1944.
Forbes is considered the Father of Art Conservation in the United States and spent most of his life traveling the world to collect various pigments that he used to authenticate classical Italian paintings.
The pigments are still used by art experts to authenticate and understand paintings.

Don't Drink The Paint Water
Ok, the title is a little misleading since a lot of the paint I'm gonna talk about in this post would have been tempera or oil, and not water-based acrylic, so there would be no paint water. But as someone who worked in acrylic and definitely accidentally drank their paint water more than once, the warning is what rings in my mind every time I think of this topic.
Tumblr media
Art is great for the soul. Art supplies, however, are not always great for the body.
Humans love smearing ourselves and our stuff with pretty colors made of shit that will kill us. Lead facepaint in Queen Elizabeth's court; Arsenic Green Wallpaper in Victorian parlors; uranium in glassware and wristwatches. And of course, all kinds of heavy metals in paints.
I talked in my post about Caravaggio about how a lot of his balls-to-the-wall batshit insane behavior may have been a result of chronic poisoning from his paints. Many artists through that whole era of history suffered from lead poisoning, to the point that "Painter's Colic" was a term for the intestinal constipation caused by chronic lead poisoning.
Now let's talk about that a little, and the various toxins that some of your favorite historical painters may have had in their systems from the creation and application of their paints...
Tumblr media
White Paint: Lead
Lead white has been used as far back at the 4th century B.C.E. by the ancient Egyptians, Greeks, and Romans, and was THE white pigment in western art up through the nineteenth century (and also appeared in works from China and Japan). It's important to note that through much of history, you didn't just go to the store and buy a tube of paint -- you made your own by grinding up pigment and adding it to a medium such as oil. To make lead white paint, artists would grind a block of lead into powder, releasing toxic dust particles into the air. The pigment's popularity largely stemmed from how thick and opaque it was, allowing for dense applications of radiant, warm white.
Lead poisoning resultantly affected a great many artists who worked extensively with lead white paint, with gastrointestinal, neuromuscular, and neurological symptoms. Chronic lead poisoning resulted in abdominal pain, nausea and constipation, as well as neuromuscular issues such as tremor, loss of coordination and numbness. Neurologically, sufferers could experience loss of short-term memory or concentration, depression, fatigue, headaches, stupor, slurred speech, and difficulty with emotional regulation, which may have contributed to the enduring stereotype of artists as erratic tortured geniuses.
Lead white would eventually be replaced by zinc white and titanium white.
Tumblr media
Vermilion Paint: Cinnabar (Mercury-Sulfide)
Cinnabar is a form of mercury sulfide (HgS) that can range in color from bright scarlet to brick-red. It is the most common source ore for refining elemental mercury-- and from both its mined form and creation via synthetic alchemy was used to create a range of red 'vermilion' pigments. Cinnabar was used decoratively dating back to antiquity due to its color, appearing in fine craftsmanship and artworks ranging from China to South America, and was the primary source of red pigment in European painting from the Renaissance to the 20th century.
And of course; it came with the fun fun experience of mercury poisoning! While ingesting cinnabar isn't nearly as toxic as other forms of mercury since the chemical composition is less reactive, cutting and grinding cinnabar to create paint pigment would lead to inhalation of particles, and the more it was ground, the brighter the red it would produce. Plus, heating cinnabar would result in the release of highly toxic mercury vapor which would damage the lungs. Long term cinnabar use would lead to renal failure, and likely other symptoms of mercury poisoning such as damage to the brain and nervous system.
Vermilion would eventually be replaced with the less-toxic cadmium red.
Tumblr media
Naples Yellow Paint: Lead + Antimony
Here's a two-for-one poisoning deal! Naples yellow -- a saturated, thick yellow that could range from pinkish orange to an almost green lemon-yellow -- is derived from lead antimonate. Inorganic and synthetically created, the pigment itself dates back to ancient Egypt and Mesopotamia, making it one of the oldest synthetic pigments (it was predated by the Egyptians' use of the yellow pigment 'Orpiment' which was made with arsenic, for even more fun!) It was first referred to as Naples Yellow in the 17th century, and became particularly popular in European painting from the mid 1700s to mid 1800s, used by artists such as Délacroix, Jacques-Louis David, and Goya.
In addition to the joys of lead as discussed above, Antimony can cause vomiting, headache, dizziness, and sleeplessness, with effects similar to arsenic poisoning.
While there were a number of holdout artists who continued to use Naples Yellow up to the 20th century, Naples Yellow was largely replaced by Chrome Yellow and Cadmium Yellow by the late 19th century.
--
These are just a few of the more popular culprits in western art history -- and not counting fabric dyes such as Scheele's Green which experienced brief and deadly popularity in the Victorian era (made with Arsenic), or Uranium Yellow pigment used in ceramics and glass, which... I think you can guess where the problem with that lay.
All of which is to say, Art Was Hazardous, and a lot of artists through history quite literally died for the dyes, sacrificing their health, sanity, and years off their lives, knowingly or not, for the colors in their masterworks.

Lab-grown pigments and food by-products: The future of natural textile dyes
As the environmental impact of the fashion and textile industries becomes clearer, the demand and need for sustainable alternatives is growing. One international research group aims to replace toxic synthetic dyes with natural alternatives, ranging from plants to microbes to food waste.
Walk into any clothing store and you'll find a rainbow of fluorescent shirts, pastel sweaters and blue jeans that rotate in and out of style each season. The colors of each garment are pristine, eye-catching and identical, but there are consequences hidden in those racks of colorful clothes.
Our planet and the factory workers producing our clothes are paying a steep price: toxic chemicals used in the synthetic dyeing process pollute waterways and soil.
Introduced in the 1860s, synthetic dyes and pigments have become commonplace in the textile industry. These dyes are part of the reason why clothes of every color imaginable are so readily available: they offer quick and easy alternatives to the natural sources of color that used to be the only option.

I've been meaning to make more posts about this, but there's so much i have to say/images to show that this will be a part 1 out of ??? and this one focuses mainly on the first batch of Purple Iris watercolors and the pH mystery they made me unravel through chaotically-organized researching.
Basically, I've been messing around with anthocyanins, a common class of plant pigments that are pH sensitive/can be used as a pH indicator. The first source I've tried has been purple irises, which i've only vaguely been familiar with in the past. The ones I picked were the ones that had begun to shrivel slightly, to the point where they were still a deep purple but picking them they would almost be leaking a purple liquid that stained my hands. I put them in a thing of hot tap water (not boiled, just the hot setting on the faucet), enough to cover the flowers, and let them steep. they began changing the color of the water almost immediately, with the fresher ones not losing their color as quickly as the ones that had begun to wilt on the plant. within 30 minutes i decided it was extracted enough.
Tumblr media
This left a strong purple in the water, which i then poured off into three other containers, two of which i would alter the pH of.
The purple is due to delphinidin, a type of anthocyanidin that forms the building blocks of anthocyanins. Note i italicize the word anthocyanidin just so it's easier to tell apart the two.
there are anywhere from 16-31 anthocyanidins depending on what source you find, but they are basically the backbone structure of anthocyanins, of which there are over 600 something. The main thing that turns an anthocyanidin (aglycon) into an anthocyanin (glycoside form) is a sugar attached to it.
Realistically, that distinction isn't useful when simply extracting things from flowers in hot water, but i thought it was a fun fact to note. Anthocyanidins also come in handy for knowing what builds the anthocyanins in your flowers/plant part;
cyanidin (30%), delphinidin (22%), and pelargonidin (18%) make up the base for a good majority of all the anthocyanins in plants (~60% collectively),
peonidin, malvidin, and petunidin being runnerups (20% collectively)
the 20-something remaining anthocyanidins make up the rest
So basically, they all have slightly different colors that are pH reactive, and can provide anything from red to pink to orange to purple to blue. But, for our purposes, if you have a blue/purple flower, that likely means it has some amount of delphinidin-based anthocyanins in it! there can also be more than one anthocyanidin type present in the same plant.
Other well-known sources of anthocyanins are grape skins, red cabbage, red onions, butterfly pea tea, and purple violets. However, they're also very abundant in many many other plants, these are just the common ones i can think of that lots of people are probably familiar with to some degree.
Fun fact, grape skins are actually really well-studied as far as anthocyanins go (i believe they mainly have malvidin-based ones) because they're so important for the coloration of wine! Anthocyanins as a whole are also studied as a natural source of food dyes, along with other flavonoids such as carotenoids.
As for why it turns colors, this is because of the way the anthocyanin changes structure in different pHs. The short answer is it turns red/pink in low pH (acidic) conditions, purple in slightly acidic/neutral conditions, and blue/green in slightly high pH conditions.
The long answer is something I'll explain in a moment, but for now here's the acid/base colors:
Tumblr media Tumblr media
(on the left, i altered it with vinegar and it became a bright magenta color; on the right, i altered it with baking soda and it became a sea green/blue cyan that refused to show up accurately on camera). That's one thing I've noticed, and others have too, is that when working with pigments (especially natural ones) the color accuracy of the camera often just completely fails. there's only so many colors a digital camera can capture!
Here's a slightly more accurate color due to different lighting, note how it's more a malachite green than a pure blue. off the bat this was interesting becuase I wasn't expecting as green of a liquid as i got.

Anyways, the first thing i did with them was use them as-is, no alterations past the addition of the respective vinegar and baking soda. I painted with them just as one would paint with watercolors, and interestingly enough, when i put them onto paper, they began to change from their pink/purple/malachite colors to a teal/indigo/emerald set instead.
This seems to be the result of something in the paper itself, likely calcium carbonate (which i only recently learned is added to "buffer" paper against acidic substances; the cellulose in paper is more stable long term when there's no acid present, and the calcium carbonate neutralizes any acids applied to a degree).
It's still interesting that even though the acids are neutralized, they give a unique color when compared to the basic paint.
I also tried soaking some of the same paper in vinegar water, which got rid of that buffer and let me paint with the pinks intact, but that's for another post.
Also, note that i said "neutral" for the middle, this is just what i wrote down for the tap water sample; in actuality the tap water is actually a bit closer to pH 6 instead of a true neutral 7, which i only found out after i had gotten this far. So whenever i say "neutral," i mean "tap water that's slightly acidic"

Here's something interesting that happened, though. Overnight i left the jars on my desk, and while the acid and neutral colors were the same when I came back ~24 hours later, the basic had degraded into a murky brown. this was interesting since that meant the instability was pH-dependent.
So, i made another color swatch with the acid/neutral/base, and used that as a comparison to look at how it had changed. Surprisingly, it painted out a yellowy-green instead of a murky gray-brown
here's the murky water that the once-malachite-green turned into:

I also poured off a bit into another container, and shifted it back into a low pH with a bit of vinegar to see if it would still change color. Surprisingly, it turned a slight pink, like pink lemonade, which means there were still anthocyanins in there but they were likely a lot less concentrated than they used to be.
Here's the pink, with a few leftover bubbles from the baking soda/vinegar reaction:

Here's the results of painting with these:

the acid was basically unchanged after sitting in a jar for 24 hours, the neutral had lost a bit of its purple color but was still about the same, and the base was now a lot yellower/tanner with a bit of green still showing through. The shifted sample was a pale stormy gray that ended up taking on a green color as it dried, as though following the trend of pink shifting to a bluer color but on a much more muted scale.
Now obviously, i wanted to figure out what caused this, so i dug around both on wikipedia and other sites but found myself eventually reading into scientific papers on the topic, at which point it became very clear that i would need to learn like, organic chemistry and such to be able to say for sure what was happening.
I did eventually manage to figure out a few things despite the dense terminology; for one thing, anthocyanins are more unstable than other plant pigments such as carotenoids. there are plenty of things that can affect their stability, including the pH of the substance they're stored in. Any higher than pH 7 (basic pHs) and theyll begin to degrade. This explains why the high pH sample lost its blue/green color, and why there was very little left to be shifted back to a pink color.
I also found out that the pH color shift isn't as simple as it seemed. Rather, there are multiple chemical forms of anthocyanins.
At the lowest pHs, basically all of them are in the "flavylium cation" state, which basically means it's positively charged and this is what gives a red color
still at a low pH (2-4), there's anothe chemical form that appears, the "quinoidal" structure that gives a blue color. Note that the red cation is still present, just no longer the only form
the more the pH rises, the more forms start to coexist, with some of those forms being colorless (one of which is a "colorless carbinol"
so, between 4 and 6 there are the cations (red) quinoidal (blue) carbinol (colorless) and something called a chalcone that gives a pale yellow
and then past that, I'm unsure, but of course that's around when the anthocyanins begin to degrade
There are also a lot more than these that i've encountered in various contexts but these seem to be the basic ones.
Do note that i do not fully understand these terms (flavylium, quinoidal, carbinol, chalcone, etc.) and have only recently begun to actually try to learn what they mean and the context surrounding them as i only had a class of basic high school chemistry under my belt prior to this. The main paper i combed over to try to find info on it seems to be behind a paywall but the DOI is:
doi.org/10.1016/j.foodchem.2008.09.001
for anyone curious and able to access it, whether through legit means or what have you.
That being said, to me, the takeaway here seems to be that there's a yellow form that appears around the time that other color forms begin to disappear, and as those degrade it makes sense that the resulting degraded forms also contribute to a murky color. This helps explain why it changed color in the jar and also retained a bit of yellow and green.
This also explains why the blue form seems to also be slightly green, it's got the blue quinoidal chemical form as well as the yellow chalcones.
There are also interesting things of note that I will get into at a later date, such as the texture/reflectivity of the way it dries, the differences in extraction ease between this and purple violets, the addition of a genuinely neutral/pH 7 sample later, a sample from a plant that doesnt seem to have delphinidins, and sample the seems to genuinely sparkle??? Much more of interest to come soon!
