Unfortunately color blindness can be caused by severe head injuries. By far the most occurences of color blindness are congenital. In very rare cases people with perfect color vision abilities can be affected by an impaired vision or color vision deficiency after a brain trauma, a stroke or some other kind of severe head injury. Such vision deficiencies are caused by a damage of the optical cortex.
Ninety-nine percent of people with color blindness have difficulty distinguishing between red and green. The absence of one pigment will cause red-green colorblindness. The absence of two pigments will make it difficult to distinguish between blue and yellow as well as green and red. Achromatopsia, the rarest kind of colorblindness, involves the absence of all three pigments. People suffering from this form of color blindness can only see in black, white and gray.
