ColorUno
Puzzle
Free · Designed for iPad. Not verified for macOS.
A daily test for your eye.
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.
— Daily challenge: same five colors for everyone, every day
— Practice mode: unlimited rounds to sharpen your eye
— Streak tracking: come back every day and climb
— Science-based scoring: not slider math, actual perceptual distance
— Share your results: Wordle-style score card to challenge friends
It's harder than you think.
- Daily reminders so you never miss a round.
- New Blind Mix mode.
- Rematch a friend instantly after a Versus game.
- Nicer share cards and a smoother daily leaderboard.
- Global Link added (so app link works everywhere in the world)
