About this app
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. FEATURES • 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 This app is intended for self-screening and educational purposes only. It is not a substitute for a professional medical examination. If results suggest a deficiency, please consult an eye-care specialist.
