ColorUno: Color Memory Game

Think your eye for color is good? Prove it.

ColorUno is a daily color memory game — like Wordle, but for your eyes. Everyone gets the same five colors each day. Memorize them, then recreate each one from memory with Hue, Saturation and Brightness sliders. One shot per day. Max score 50.

Scoring uses CIEDE2000 — the perceptual color-distance standard used to calibrate professional displays. If it looks close to a human eye, it scores close.
