## What is ColorUno?

Huely is a daily color memory game. You have a few seconds to memorize a color — then it disappears. Recreate it from memory using Hue, Saturation, and Brightness sliders. Your score is measured using CIEDE2000, the same color science used in professional display calibration.

Five colors per day. Max score 50. One shot.

— Practice mode: unlimited rounds to sharpen your eye
