Colour Blind?

Inspired by the National Gallery's latest exhibition Making Colour, which I previewed a few days ago (CLICK), BBC News has posted an interesting article on colour blindness. This beautiful, eye-catching painting is by colour-blind artist Justin Robertson, who has a problem with flesh tones and used to avoid them (CLICK). I know one severely colour-blind man who cannot tell the different between the colours of traffic lights. He has to judge by their position. If you want to check your own vision, CLICK for a colour blindness test.
