Chroma

Each round, you get five seconds to absorb a photograph — its warmth, its shadows, the exact balance of color across the frame. Then a shift is applied, and your job is to drag the tones back to where they started. It sounds straightforward until the third round, when the shift is subtle and your memory of the original is already fading.

Chroma sits in an interesting corner of puzzle games: it trains genuine perceptual skill rather than reflex or logic. Photographers and designers will likely spot an edge here, but anyone who pays attention to how colors feel can improve quickly across the five-round session.

Scores are based on precision, so there's real distance between a careless guess and a careful one. It plays best on a calibrated monitor or a phone screen with brightness turned up — accurate color reproduction makes a noticeable difference in how fairly you can judge your own adjustments.
