While the natural world paints its own picture, the colours we choose in the spaces we live, and work are deeply personal. From burnt orange to mission brown, when it comes to colour trends for the home historian of architectural paint Patrick Baty has seen them all. He's advised on paint colour for Buckingham Palace, Hampton Court Palace, Tower Bridge, 10 Downing Street, and even BBC's Broadcasting House. He has written two books on the range and history of colour, Nature's Palette and Anatomy of Colour and The Story of Heritage Paints & Pigments.
