Unity In-Game Color Picker - Customize Characters in 2D Games

I wish more unity tutorials were more like yours, you have the source code and everything and you explain what everything is supposed to mean and it helps a lot!

Any idea how to allow the player to do this on just part of the sprite? Like just the body of your unicorn and not on the horn?

great video, thank you. I am building a "Paper Doll" game and want to allow players to choose their own colors for outfits and such.
