Colour code

People who are colour-blind are often at a disadvantage when it comes to using public displays and colour-coded systems. Now, availability of computer-controlled colour displays has made it possible to simulate how colour blind-people perceive a complex colour screen.

Scientists at France's Museum National d'Histoire Naturelle have @eveloped a computer algorithm that converts a colour video picture into what would see a colour blind person. Their work is based on the colour perceptions reported by people who are colour-blind in 1 eye.
