A researched study on two of art's most fundamental themes, Colour and Light bridges the gap between abstract theory and practical knowledge. Beginning with a survey of under appreciated masters who perfected the use of colour and light, the book examines how light reveals form, the properties of colour and pigments, and the wide variety of atmospheric effects. Gurney cuts through the confusing and contradictory dogma about colour, testing it in the light of science and observation. A glossary, pigment index, and bibliography complete what will ultimately become an indispensable tool for any artist.
