Color Mixer is a five-round color-matching game. Every round shows a target color and three sliders for red, green and blue. Your job is to mix exactly the right amount of each primary light so your color lands on top of the target. The closer you get, the higher your score.
Unlike the memory variants, the target never disappears. There is no flash to remember and no clock counting down. Color Mixer is about precision and about understanding how additive color works: red and green make yellow, all three at full make white, and everything at zero is black.
How additive color mixing works
Screens build color by adding light, not by mixing paint. Start from black and add red, green and blue. Equal amounts of all three give you a neutral grey or white. Pull one channel down and the color drifts toward the complement of that channel. Learning to read a color as “a lot of red, some green, almost no blue” is the core skill this game trains.
Scoring
Each round is scored on perceptual color distance using the CIEDE2000 metric — the same color-science standard the rest of the site uses. A perfect match is 10 points, and the curve is forgiving enough that a close mix still scores well. Five rounds gives a 50-point ceiling. Clearing 45 means you have a genuinely good eye for color.
