Quizplus · Accepted Answer

Anomalous trichromats are the most common type of color vision deficiency, accounting for about 75% of cases. They have three types of cone cells in their eyes, but one type is slightly altered, resulting in difficulty distinguishing between certain colors. Protanope dichromats and tritanope dichromats are less common types of color deficiency, while monochromats have a complete absence of color vision.
