Wave World How light makes the colours we see

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. 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. Teacher notes: When teaching about colours and the different frequencies of light, this video could be used to check students’ understanding of the differential reflection and absorption of light by different coloured objects. Teachers could freeze the film at relevant points and take feedback from students. Students could then be asked to design a set and costumes to illustrate a particular special effect on stage using coloured light. Students should know the names of the primary and secondary colours of light. Teachers could link the science to careers, e.g. lighting technicians and fashion designers.
