A grid of colored squares will appear. One square has a slightly different shade — tap it before time runs out. 3 lives, increasing difficulty.
FAQ
This test measures your ability to distinguish subtle differences in color hue, saturation, and brightness. It assesses the sensitivity of your cone cells and color processing pathways.
While the number of cone cells is fixed, practice can improve color discrimination by training the brain to detect subtler differences. Artists and designers often develop superior color perception.
Screen quality, ambient lighting, color blindness, age, and fatigue all affect results. For best accuracy, use a calibrated screen in neutral lighting and take the test when alert.
About this test
The color perception test measures how precisely you can distinguish between similar colors. It reveals the sensitivity of your color vision system.
How It Works
A grid of colored tiles includes one tile with a slightly different shade. Find the odd one out. The color differences become increasingly subtle with each level.
Color Vision Science
Human color vision relies on three types of cone cells sensitive to red, green, and blue wavelengths. The brain combines their signals to perceive millions of colors, but the precision varies between individuals.
Tips
- Use a good quality screen with accurate colors
- Reduce screen glare and ambient light reflections
- Scan the grid systematically rather than randomly
- Squinting can sometimes make subtle differences more apparent
