What is colour blindness?

Answer: 

The vast majority of people with colour blindness can see many colours, but have problems distinguishing particular colours. Colour blindness is a genetic condition affecting the colour sensing cells in the retina of the eye. Around 8% of males and 0.5% of females are born colour blind. In 99% of cases, red and green are the colours that are difficult to distinguish.
