Join the art historian and BBC broadcaster for a global history of civilisation through the lens of colour. He explores our relationship with colour, from the black nothing that preceded existence to the gilded gods of antiquity, the blue horizons of the age of discovery and the defining colour of our current fight against climate change. Examining the work of artists, scientists, writers, philosophers, explorers, and inventors, he shows that colour is more than surface decoration. He demonstrates that it is a symbol, a metaphor – and as fundamental to who we are as language – to art historian, presenter and curator Katy Hessel.
