Score: 0Time: 60s
How to play the color test
Tap “Start.” A grid of squares appears, all the same color except one, which is a slightly different shade.
Tap the odd square out. Each hit is worth one point, and the next level has more squares and a smaller difference.
You have 60 seconds. Wrong taps don’t cost points, but they do cost time. Your best score is saved in this browser.

Does screen brightness matter?
Yes. Dim screens or a blue-light filter make the differences harder to spot.

No. This game measures how well you notice tiny differences in shade. To check for color blindness, try our color blind test.
