About this test

Among tiles of the same color, one is slightly different. Find as many as you can in 60 seconds. As you level up, the grid grows from 2×2 to 8×8 and the color difference shrinks from 14 to 1.2 perceptual lightness points. Colors are built in a perceptual color space (OKLCH), so every hue is equally hard at the same level. Wrong taps cost 3 seconds. Differences use lightness only, so the game stays as fair as possible for color-blind players, but results vary with screen brightness and device. It is a game, not a vision or color-blindness test.
