Hue Hunt

A timed colour-acuity test: find the single off-shade tile each round, and every hit shrinks the difference closer to the limit of human vision.

How to play

A short calibration learns which colour axis your eye reads best, then the run begins. Each round shows a grid of nearly identical tiles with one shade off — tap it before the timer drains.

• Tap the odd tile fast; correct picks shrink the colour difference for the next round (harder), misses grow it.
• Each round is on a 6-second clock; running out counts as a miss.
• Finish the fixed set of rounds; faster, finer catches score more.
• Your finest caught shade (in delta-E) is reported at the end.

Controls

• Desktop: click the off-colour tile; click Daily or Practice and New run.
• Phone & tablet: tap the tile — built for touch.

Tips & strategy

• Scan for the tile your eye keeps drifting back to rather than checking each one in turn.
• Trust the calibration — the game biases toward the axis you read best, so commit quickly.
