Cool idea to make a color mixing game. I was first very confused on how to play it, but maybe because I know nothing about color theory :). However, I realized that you do not really need to know color theory, you just need to understand where you want to move on the wheel and where you need to aim for that (usually double the distance on the circle). I think the idea is pretty cool, but might need some tweaking to bring the theme a bit more through. Maybe you still try to go with a more complex approach which really relies on color theory and how mixing color works. Would at least be worth a try.
Congratulations to your entry!
