Colours of light
White light, like sunlight, is not one colour: it is a mix of many colours. A prism, a glass of water or a raindrop can split it into a band of colours that always come in the same order: red, orange, yellow, green, blue, indigo and violet. Sent into a second prism, the colours mix back into white light.
