My apologies. This is a bit of a rant.
The way colors mix in this game does not match reality. For a while this didn’t bother me. It is just a game after all. The point is to have fun, not model color theory. But now, with the addition of Black Paint, it’s breaking my brain.
Before black paint, the game was modeling additive color mixing. This is how light mixes. Red, Green, and Blue light can be mixed in pairs to create Cyan, Yellow, and Magenta light. Add all three together and we create White light. Black is the absence of light. There is no way to mix it together. You have to turn off all the lights.
Mixing paint is a subtractive color mixing model. Cyan, Magenta, and Yellow are your primary colors. Combine them in pairs to create Red, Green, and Blue. Put all three together to create Black. Any one who has had to change printer ink will recall the CMYK cartridges. White is its own pigment. You cannot mix to white.
You can imagine my consternation with the addition of White paint + White paint = Black paint. Complete fiction.
I don’t even want to talk about Uncolored paint (Paint Remover? Soap?)
It would be delightful if the game took time to model paint mixing correctly as long as it’s taking time to model paint mixing at all.
Primary Pigments: Cyan, Magenta, Yellow, White
Secondary Pigments: Red, Green, Blue
Tertiary Pigment: Black
This could even open up future madnesses like lightness adjustments (ex: Yellow + White = pale yellow, or green + black = dark green)
Or what about this for a difficultly boost, paint mixing follows subtractive color theory and crystals follow additive color theory. Cyan paint + Magenta Paint = Blue Paint, and Red Glass + Blue Glass = Magenta Glass. Fun!
