My Minecraft server uses the Artmap plugin, which allows you to paint on 32x32 pixel canvases with 54 dyes. Each dye (except white, black, and transparent) can be made 2 steps darker and 1 step lighter, leading to 4 variations per dye. As a result, I decided to compile them all.
The colours are ordered as: Dark 2, Dark 1, Original, Light 1, and each set of 4 is followed by the next dye's palette.

I painted all the dyes on canvas ingame, took a screenshot, then extracted every colour through an editor. I then listed out every hex code. To my Minecraft artists: I hope this helps!
