Color blindness is caused by a problem in the eye cones that inhibits the ability to tell the difference between some or all colors. There are three types of cones in the eye, with each being sensitive to either blue, red or green light. When one or more cones are not functioning properly, color vision problems may occur. Very few people see no color at all.WebMD: Color Blindness - Topic Overview
