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.
If your eyes are normal, you can distinguish different colors, but if your cones lack one or more light-sensitive chemicals, you may see only two of the primary colors. Poor color vision has several causes: Inherited disorder. Inherited poor color vision is much more common in males than in females. The most common color deficiency is red-green, with blue-yellow deficiency being much less common. It is rare to have no color vision at all. You can inherit a mild, moderate or severe degree of the disorder. Inherited poor color vision usually affects both eyes, and the severity doesn't change over your lifetime.
