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

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.
