idk if it's possible but a colour wheel for the text? so it's more than just those 7 colours tumblr gives us

I would love to do this one, but off the top of my head I think it's basically impossible for technical reasons (the post editor is really complicated; the fact that Quick Tags can work in it is sort of a stroke of luck). Might look into it at some point to see if I'm wrong, though.
