Abstract
The aim of this study was to determine how much information about surface colour is preserved under changes in daylight illumination. Information was quantified in the sense of Shannon and was estimated separately for chromatic and achromatic attributes of surfaces in natural scenes. Despite the large variation of luminance within natural scenes and the usually restricted gamut of colours, the information from chromatic attributes was only a little less than that from achromatic attributes. As well as providing a basis for object discrimination in natural scenes, chromatic attributes provide an important contribution towards object identification under changes in illuminant.
