Colour: The Spectrum of Science

`Colour: The Spectrum of Science' is a three-part documentary following Dr Helen Czerski as she explores the facts behind Earth's colours. Using a set of 15 colours as a guide, the physicist goes on a journey to discover how a colourful world was created from a baron grey rock. In California, Czerski uses the largest solar telescope in the world to break down the science behind sunlight. The episodes reveal how sulphur atoms can create vivid blues, why red ochre signifies life and where gold really comes from.
