Ocufuse games are for fun and screen breaks. They are not a vision test and do not diagnose or treat any condition. See an eye care professional for any concerns.
How to play
- Press Start. A grid of tiles appears, all the same colour except one.
- Tap the odd tile. On a keyboard, move with the arrow keys and press Enter.
- Keep going until the 60 seconds run out. A wrong tap takes 2 seconds off the clock.
Levels and scoring
Your score is the number of odd tiles you find in 60 seconds. The first grid is 2 by 2 with an easy difference. After that the grid grows to 3 by 3, 4 by 4, 5 by 5 and finally 6 by 6, and the difference in lightness shrinks with every find, from 24 percent at the start to about 2.5 percent. Each grid picks a new random colour, so some levels are harder than others. Your best score is saved in this browser.
Tips for a high score
- Take in the whole grid at once instead of checking tiles one by one. The odd tile often stands out at the edge of your view.
- Sit straight in front of the screen. On many laptop screens, the viewing angle changes how colours look from top to bottom.
- Turn off night mode, warm screen filters and this site's eye comfort mode for your best score. They make shades harder to tell apart.
- When you are stuck, a quick guess costs only 2 seconds, which can be cheaper than staring.
- Many people see some colours differently, and colour vision deficiency is common. That is normal, and nothing here measures it.
Questions about Shade Hunt

Does it work on my phone?
Yes. It works in any up-to-date browser on a phone, tablet or computer, with touch, a mouse or a keyboard. The game pauses by itself if you switch tabs.
Is this a colour blindness test or a vision test?
No. Shade Hunt is a game for fun and screen breaks. Screen brightness, display settings and room light all change how the tiles look, so a score says nothing about your eyes. If you notice a change in how you see colours, see an eye care professional.
Why do some rounds feel harder than others?
Every grid uses a random colour, and most people pick out small differences in lightness more easily in some colours than in others. Pale yellows and very dark blues are often the hardest.
