Your score is the percentage of the 8 plates you got right. A higher score suggests better color discrimination — this is a casual screening result, not a medical diagnosis.
Your monitor's color calibration, screen brightness, and ambient lighting significantly affect color discrimination. Night mode or blue-light filters can distort colors and skew your result.
People with normal color vision typically get 7-8 out of 8 plates correct. Scoring 4-6 correct may be borderline, and 3 or fewer suggests a possible red-green deficiency worth following up on.
Red-green color vision deficiency is the most common type of color blindness, affecting roughly 8% of men and 0.5% of women of Northern European descent. It's usually caused by a gene variant on the X chromosome, which is why it's far more common in men. The Ishihara test that inspired this screening method was devised in 1917 by Japanese ophthalmologist Shinobu Ishihara.
Daily/weekly/monthly rankings collect each user's best score recorded within the last 24 hours, 7 days, or 30 days. The all-time ranking includes every record since the site launched.
When multiple users share the same score, whoever recorded it first is shown at the higher rank.
Q. My result seems off — am I really color blind?
A. This is a casual screening test for fun, not a medical diagnosis. If you're concerned about your result, an actual eye exam is the way to get a proper diagnosis.
Q. Can results vary between monitors?
A. Yes — cheaper monitors or devices with a screen protector applied can render colors differently, which can shift your result.
