The largest group of color deficient individuals (6%) is still trichromatic, but they have anomalies in their individual cone sensitivity curves. Congenital color vision defects are usually symmetric and almost always remain stable. Congenital color vision defects are overwhelmingly red-green in type and occur almost exclusively in males, being linked to the X-chromosome in many varieties of allelic forms.
