How scoring works
Scores use perceptual color difference (ΔE 2000). A perfect match is 100 points. Group challenges average the match for every color. Display settings can change what you see.
Train your eye for hue, saturation, and lightness
- Choose Match a color, Recall a color, or Against the clock for five rounds. Learn color skills walks through six skills in twelve rounds.
- Use the color field and sliders to match hue, saturation and lightness. Teaching rounds show only the adjustment being practiced, then introduce complementary, analogous, triadic and tetradic palettes.
- Recall mode reveals the target for five seconds; timed mode allows 30 seconds per round. After checking a match, read the feedback and choose Next color. Every target and guess appears in the final review.
- Choose Play again from your results for a fresh game, or try the daily challenge. Share challenge sends the same targets and settings; Copy score copies your completed result with a link to that challenge.
A hue can be close while its lightness is noticeably different. Feedback suggests making the match lighter, darker, more vivid, more muted, or adjusting its hue. Scores are a game measure, not a vision assessment.
