Color-Blindness Test is a simple, ad-free way to check your color vision using the classic Ishihara plate method. Color blindness is the inability to distinguish between certain colors. It results from a deficiency of color-sensitive pigment in the cone cells of the retina. The most common form is red-green color blindness, where red and green are perceived as the same color. Roughly 8% of men and 0.5% of women are affected, most of them from birth.

It is not a substitute for a professional medical examination. If results suggest a deficiency, please consult an eye-care specialist.
