ColorMatch
See a color. Recreate it from memory.
5 rounds. A colour flashes for 3 seconds — then you rebuild it from H/S/L sliders. Score is based on how close you get.
About ColorMatch
ColorMatch is a visual memory game where a random colour flashes for three seconds (one second in Hardcore), then disappears and you have to rebuild it from memory using Hue, Saturation, and Lightness sliders. Scoring is based on how different the two colours actually look to your eye — not on the raw numerical gap between the slider values — so a small mismatch in a region your eye is sensitive to costs more than the same numerical mismatch in a less-sensitive region. The game runs five rounds for an average out of 100. Free, no account, plays on any device.
How to play ColorMatch
Watch the colour fill the screen with a countdown overlay in x.xx s format. When it disappears, three sliders let you rebuild it: Hue is the rainbow wheel (0–360°), Saturation goes from grey to fully saturated, Lightness goes from black through your colour to white. Each slider's track shows a live gradient based on the other two channels — so you always see what you're picking before you commit. Hit Lock it in to submit your guess.
Tips for higher scores
Get the hue right first — it's by far the dominant signal in colour perception, and most matching errors are in saturation or lightness. If the colour looked pastel, expect lower saturation; if it looked vivid, expect saturation around 70–90. Mid-greys hide hue almost completely, but the targets are clamped to S ≥ 30 and L ∈ [30, 70] so you'll never see a flat grey or near-black/white. In Hardcore the one-second view is enough if you focus only on hue first.
