What Is Color Blindness?
Color blindness, or color vision deficiency (CVD), is a condition where certain colors are perceived differently or cannot be distinguished. The most common types affect red-green perception: protanopia (no red cones), deuteranopia (no green cones), and tritanopia (no blue cones). Achromatopsia, the rarest form, results in complete absence of color vision.
