Color Memory Game

The Color Memory Game is a free online color guessing game that tests how well your eyes remember color. You see a target color for a few seconds, then recreate it from memory using three sliders — hue, saturation, and brightness. Five rounds per game, scored out of 50.

Click Play Solo to start. A color fills the screen for four seconds in Easy mode (or three in Hard). When it disappears, drag the hue, saturation, and brightness sliders to match what you just saw. Submit your guess and see your score. After five rounds you get a final total out of 50.

Easy mode shows a Ready–Set–Go countdown on a black background, then reveals the target for a full four seconds. Hard mode flashes three decoy colors on the Ready, Set, and Go words, and only gives you three seconds on the real target — so you have to lock on fast while the decoys try to scramble your memory.

Scoring uses real color science, not raw slider math. Both colors are converted to CIELAB and compared with CIEDE2000, the industry standard for perceptual color difference. That distance becomes a 0–10 score on a sigmoid curve, with a recovery bonus for nailing the hue and a penalty for missing it on vivid colors. Getting the right color family is what counts most.

Yes. On phones the color fills the whole screen with vertical sliders on the left for one-handed play. On desktop the game plays in a centered card. It's a browser game — no app install, no signup.

Completely free. No signup, no paywall, no purchases. Just pick Easy, Hard, or a multiplayer room and start playing.

Regular play helps you notice subtle differences in hue, saturation, and brightness — the same way ear training sharpens pitch. Designers, photographers, and artists often use color memory drills to develop a reliable eye for color.
