Although we experience colour all the time, do we really understand colour? Three hundred years ago Isaac Newton showed that white light is composed of all the colours of the spectrum yet does this provide us with insight into our own personal experience of colour sensation? To answer such questions on the nature of colour this volume gathers the combined knowledge of physics, biology, history and art. It provides an exciting exploration of colour, from the diverse perspectives of experts in eight different fields of study. Their essays take us on a journey both through the sciences and the world of fine art, and they combine to give a full and rewarding view of colour.
