Genetically inherited – or acquired through illness, accident or poisoning – colour blindness is a condition affecting approximately 8% of men and 1% of women in developed nations. The absence or altered sensitivity of one of the three cone receptors at the back of your eyes causes the individual difficulty in distinguishing certain colours from one another. While not a disability, the condition can at times be frustrating. I’m sure anyone with a form of colour blindness has fielded many a ‘what colour does this pencil look to you?’ question ad nauseam.
