Frequently asked questions
What does the odd-one-out color test measure?
It tests color perception — your ability to spot a tile that is a slightly different shade. The difference shrinks each round.
Is this a color blindness test?
No, it is a fun perception game, not a medical test. But people with strong color vision tend to score higher.
How do I reach a higher level?
Scan the whole grid for the tile that stands out, and play in good lighting with screen brightness up.
