No - colour-blindness is the inability of the brain to interpret correctly colours that the eyes see, or maybe the eyes have a defect in their structure that sends the wrong signals to the brain.

Maybe the optic nerve is damaged, or the eyes themselves are damaged - there are various medical reasons for the cause of blindness.
