Physics: Making White Light from Red, Blue and Green
See red, green and blue light overlap in a simple demonstration, revealing how coloured light can combine to appear white.
Explore light, rainbows, eyes and the surprising ways colour appears in nature, art and the world around us.
Colour can begin with sunlight passing through a prism, a bright flower seen by a bee or a message travelling from the eye to the brain.
