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.
This is the most common type of color blindness. If a different pigment is missing, you may have trouble seeing blue-yellow colors. People with blue-yellow color blindness often have problems seeing reds and greens, too. The most severe form of color blindness is achromatopsia. This is a rare condition in which a person cannot see any color, only shades of gray. Most color blindness is due to a genetic problem. About 1 in 10 men have some form of color blindness. Very few women are color blind. The drug hydroxychloroquine (Plaquenil) can also cause color blindness.
