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

• 50 high-resolution Ishihara test plates
• Tap to erase the dotted overlay and reveal the correct answer
• Clean, modern interface — no ads, no sign-up, no tracking
• Works fully offline on iPhone and iPad
• Light and dark mode support
