We live in a world ablaze with colour. From rainbows and rainforests to oceans and humanity, Earth is the most colourful place we know of. But the colours we see are far more complex and fascinating than they appear. In this series, Dr Helen Czerski uncovers what colour is, how it works, and how it has written the story of our planet. There are also the colours that we can’t see, the ones that lie beyond the rainbow. Each one has a fascinating story to tell.
