About this app

Curious how your color vision compares to most people's? This is a quick self-check you can do in about two minutes.

You will see 15 plates filled with colored dots. Inside each one, a number is formed by dots in a different hue. Type what you see, or tap "I can't see a number" if nothing stands out. At the end you get a summary of how your answers leaned.

WHAT YOU GET
- 15 dot plates covering red-green and blue-yellow ranges
- A plain-language summary of your result
- A breakdown by category, so you can see where your answers differed
- Share your result with a tap

BUILT TO BE SIMPLE
- Works fully offline, with no account and no sign-up
- No camera, microphone, location, or storage permissions
- Nothing about your answers leaves your device
- Dark mode included

HOW TO GET A USEFUL READING
Your screen is part of the check. For a more consistent experience:
- Use even, indirect lighting rather than direct sun
- Set your screen to a comfortable brightness
- Turn off night mode, blue light filters, and any color adjustment
- Hold the phone at a normal reading distance
- Answer with your first impression instead of studying each plate

A NOTE ON WHAT THIS IS
This app is made for curiosity and self-checking. It is not a medical test and does not replace an eye examination. Screens vary widely in how they render color, and lighting changes what you see, so results shift from device to device.

If you have questions about your color vision, or if a result surprises you, talk to an eye care professional. They can do a proper assessment with equipment made for it.

Around 1 in 12 men and 1 in 200 women see color differently from the majority. Most people who do have lived with it their whole lives without thinking about it much. If that turns out to describe you, it is simply one more thing to know about how you see the world.
