Thanks for all the feedback and advice! I do appreciate everything everyone has to say about the game, and plan on incorporating ideas in a future update. I've given the color mixing a lot of thought, and I agree it can be unintuitive the first time you encounter it, but I think the additive color model is core to the gameplay. Perhaps my nerdy love of science is misleading me from what the average player would enjoy, but I'm trying to simulate the way light really does mix - because, well, it's a game about light. Perhaps I could add the option to play with a more traditional color mixing scheme?
I think you should stick with the existing scientifically accurate color scheme for the mixing of lights. I have a young child and if he were confused by it I would find it an excellent opportunity to explain something new to him.
I think keep it as is, but use it as an opportunity to explain the difference, perhaps? I imagine this would be great for scientifically-minded kids to learn from.
I actually do explain the difference if you explore deep enough into the app (maybe it's too difficult to find) - if you click on the color reference button in the gameplay so that the color palette pops up, there's a button at the bottom called "Learn more about colors" that brings you to a multi-page explanation on the additive vs subtractive color models.
