Colour blindness is not a form of blindness, but a deficiency in the way you see colour. This is a genetic condition.

With this vision problem, you have difficulty distinguishing certain colours, such as blue and yellow or red and green. Colour blindness testing can help determine the kind of colour deficiency you have. Red-green colour deficiency is the most common form of colour blindness.
Currently, there is no cure for colour blindness. But some coping strategies may help you function better such as using special lenses to enhance colour perception or some filters available in either contact lens or eyeglasses.
