This free color blind test uses Ishihara-style dot plates drawn fresh in your browser: a number hides among colored dots that match the background in brightness and differ only in hue. Each run shows 8 plates with new random one- or two-digit numbers, so you can't memorize the answers. Type what you see or tap "I can't see a number"; 7–8 correct reads as typical color vision, 4–6 as borderline, and 0–3 as worth a closer look. It is a just-for-fun screening, not a diagnosis: screen settings, night mode and lighting all shift the result, and only an eye exam with an optometrist or ophthalmologist can confirm a color vision deficiency.
Frequently Asked Questions
Q. How does this color blind test work?
A. You read 8 Ishihara-style plates and type the number hidden in each one. The numbers (2–99) are randomly generated every run, and the number and background dots differ in hue rather than brightness.
Q. What does my color blind test score mean?
A. 7–8 correct suggests typical color vision, 4–6 is borderline, and 0–3 means many numbers stayed hidden. A low score can come from a color vision deficiency, but also from a dim screen, night mode or glare, so retest in good light before reading much into it.
Q. Can it tell which type of color blindness I have?
A. No. It gives a single score and does not separate protan, deutan or tritan types or measure severity. That takes an in-person exam with an optometrist or ophthalmologist, for example with printed plates or an anomaloscope.
Q. How common is color blindness?
A. Red-green color vision deficiency affects about 8% of men and 0.5% of women of Northern European ancestry, and around 5% of East Asian men. It is usually inherited on the X chromosome, which is why it is far more common in men.
