Which grey stands out more?
A four-minute experiment on how people actually see contrast, on their own screens, in their own rooms. You will see two cards at a time and tap the one that pops more. There are no right answers.
Sixty quick taps. Your first impression is exactly what we want.

Where are you right now?
Room light changes how dark greys look. Pick whatever is closest.
2 / 2
How many squares can you see?
Some are very faint. Take a moment, and don't tilt your screen.
Here's how it works
You'll see two cards. Each has a square in the middle. Pick the card where the square stands out more from its background.
Tap a card, or use the arrow keys. Three practice rounds first.
That's all there is to it.
Now sixty for real. Some will be easy, some will feel like a coin toss. Both are useful. Go with your gut.
A few use words instead of squares; same question.
Done
Thank you. Your eyes just became data.
Your screen
Which formula sees like you?
| You | Everyone |

How often each contrast formula picked the same card you did.
Consistency
This one needs true colours.
Your browser is using forced or inverted colours (a high-contrast or accessibility mode). That's a good thing to have, but it changes every grey we'd show you, so the answers wouldn't mean what we need them to.
If you can, try again on another device or with that mode off. Thank you for stopping by.
