Quick Test - What number do you see?
A Quick Look At Color Vision
This Color Blindness Test uses Ishihara-style plates, the familiar circles filled with coloured dots that hide a number. People with typical colour vision read one figure, while those with a colour vision deficiency may see a different number or none at all. Working through the plates takes only a few minutes and gives you an instant, easy-to-read result that hints at whether your colour perception follows the common pattern.
The most widespread type affects how red and green are told apart, while blue-yellow deficiencies are far rarer. Many people live with a mild deficiency without realising it, since everyday tasks rarely force the issue. A simple screening like this can explain small puzzles, such as why certain charts, maps, or status lights feel harder to read than others say they should be.
Reading Your Result Sensibly
This is an informal screening tool, not a medical diagnosis. Screen brightness, colour settings, and lighting all affect how the plates appear, so a single online result should never replace a proper examination. If your result is unexpected or you have ongoing concerns about your vision, an eye care professional can run accurate, calibrated tests and explain what they mean for you.
