That’s probably the most creative and unique mechanic I’ve seen so far! Though it was really hard to figure out at start since the game doesn’t show any tutorial or tips, and ~10 first levels can be solved in a second by accidentally moving the mouse :D (I do realize that the game’s page has an explanation of mechanics, but I prefer to see the games “raw” first, so to speak). The last levels were mostly just trial and error, and, again, I completed most of them almost accidentally.
I think this is a great mechanic to iterate and build up on, great job and congrats with your submission! I’d be happy if you tried my game as well, it’s also about colors: https://lisyarus.itch.io/color-fractory
