We live in a world ablaze with colour. Rainbows and rainforests, 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…


In the first episode, Helen seeks out the colours that turned planet Earth multicoloured. To investigate the essence of sunlight Helen travels to California to visit the largest solar telescope in the world. She discovers how the most vivid blue is formed from sulphur atoms deep within the Earth's crust and why the presence of red ochre is a key sign of life. In gold, she discovers why this most precious of metals shouldn't even exist on the surface of the planet and in white, Helen travels to one of the hottest places on Earth to explore the role salt and water played in shaping planet Earth.

The raw, early Earth had plenty of colour, but that was nothing compared with what was going to come next. That canvas was about to be painted with a vast new palette - and the source of those colours was life. Green is the colour of the natural world and yet it's the one colour that plants have evolved not to use.

The colours that we see are only a fraction of what's out there. Beyond the rainbow there are colours invisible to our eyes. In this episode, Dr Helen Czerski tells the story of scientific discovery. To see the universe in a whole new light, Helen takes to the skies in a NASA jumbo jet equipped with a 17-tonne infrared telescope.

In each episode, geologist Dr. Iain Stewart explains the effects and importance of a specific force of nature, such as wind or volcanism. He also examines the various ways in which it shapes planet earth itself and influences life on it, often in conjunction with other natural forces, and sometimes with lifeforms, as in the 'apocalyptically' grave case of global warming.
