Color Memory Game

How to play

A color flashes for 4 seconds, then vanishes — recreate it from memory with hue, saturation, and brightness sliders. 5 rounds, each scored 0–10 by perceptual color difference, up to 50 points. Everyone gets the same 5 colors, with one leaderboard run, streaks, country rankings, and 18 variants from speed and gradient to multiplayer rooms.
