Description
Photograph of a man's shadow from the Science Museum's Optics gallery illustrating the way colours mix. Three projector lamps which give out red, green and blue light mix together on a large screen to produce white light. A person standing in front of the lamps then produces overlapping, multicoloured, shadows on the screen.
