      It’s usually a problem with the eyes. Your eyes have three different types of cells for perceiving different colours, and when one or more of these cell types or their connections to the brain are faulty, it causes colour blindness. Scientists believe colour blindness is usually a condition caused by genetics, but sometimes you can get it as a result of an illness (such as diabetes, multiple sclerosis, or different eye diseases)
