- jrapdx3 12y agoCertainly depends on the source. But I believe you are about right. I wrongly trusted memory for the stat. The figure I used applies to a subset, green perception impaired males, which is around 5-6%, depending on level of impairment considered. As you note, including the red perception impaired adds ~2% of males. And about 0.5% of females are also color-vision impaired. Overall it is around 9% of the US population. The prevalence of color-blindness varies by racial/ethnic criteria, and between groups male/female ratio varies quite a bit. Color vision is a very fascinating subject.
