I know. I still want it! Lol.
I think it would be super interesting.
Just for moments of being able to modify what color changes when on the changers. So I could heal and get a color attack potentially. I think that would work. Or they need their skills to be more direct. Turn purple to yellow and a yellow to brown. No wait. Gah tired. There is something amazing here waiting to be tapped. I can feel it!
