Jon Chase is at Leeds College of Art. The art students here know a thing or two about colour, so they’re taking part in an experiment. Can they work out what happens when light reflects off paints of different colours? One team of students paints the words RED, GREEN, and BLUE, in each of the colours, red, green and blue. The other team has to work out which one is painted in its correct colour. Not so easy when you can only see them in black and white. It’s to do with differential reflection – which colours are absorbed, and which are reflected.
In the studio, Jon makes white light by mixing different colours. And he reveals some amazing art from Italy that uses the rules of colour reflection to paint three different images on the same piece of paper.
