In this penultimate episode of the Colour of Sound series we visit Isaac Newton as he investigates the nature of light and colour. It was Newton who formally identified the ROY-G-BIV colour spectrum after his experiments passing light through glass prisms.
Newton also attempted to connect colour with sound, a move which is often seen as an embarrassing blip in his career. He described each of the seven colours as musical intervals. Indigo, the colour of the supernatural, was described as a 6th interval.
