hello! i'm bored rn so i got started on a couple color schemes ^^ i haven't filled out the secondary/tertiary parts yet but hopefully this is helpful somehow LOL
y2k - according to the aesthetics wiki, the key colors for y2k are "Silver, blue, bright, and vivd colors;" i also gave the y2k aesthetic institute another cursory glance while i was picking :o you could maybe add some more neons to this? but i feel like while all colors are technically used, lighter and cooler colors are heavily emphasized...? idk if anything might want to add the neon/light oranges or darker grays
webcore - based on web-safe colors and the original mspaint color palette! there are murky colors in both of those but i decided not to include them bc i never see them in webcore pics? like when you think ye olde angelfire/geocities sites, i never think of like. brown LMAO but again that's just me trying to differentiate this aesthetic from the others
synthwave - according to the aesthetics wiki, key colors are "Magenta, pink, blue, purple, cyan, black," and sunsets/dusk are a major motif; the other neons are included bc
it's 80s i could see them used as good accent colors :o
vaporwave - this aesthetic is so hard to pin down idk this probably needs a lot of work
sky - in the same vein as the food colors, but it's sky words! there were less than i thought LOL
plants - color names also used for flowers, fruit, wood, etc! i forgot periwinkle but i don't feel like adding it
seaside - same concept as above. periwinkle is here too bc it's a species of sea snail, although it should be noted they are not the same color as the periwinkle flower! i have too much useless knowledge crammed in my head!
