This book, by one of the leading scientists on the subject, introduces the relatively recent domain of color appearance. That is, the study of the *subjective* appearance of colors, depending on their surrounding, background, context, etc. The emphasis is thus on the various effects which affect our perception of colors (light intensity, background, simultaneous contrast, etc.) and their modeling.

A must have for all those working with colors. The presentation is very educational, the visual illusions are fascinating, it is both a pleasure to read and an excellent reference to consult on the subject.

It introduces human vision and the perception of colors, the field of psychophysics and its methods, colorimetry (the objective study of physical colors), and the rest of the book is dedicated to color appearance itself. Important terminologies are discussed (e.g. the crucial difference between luminosity, brightness and lightness), then color systems (Munsel, etc.), then the various effects which affect the appearance of colors, viewing conditions, chromatic adaptation, perceptually uniform color spaces, and analytical color appearance models. Different models are reviewed and compared (Hunt, Nayatani, RLAB, preversion of CIECAM). Finally applications and device-independent imaging are described.

Note that this book is not a book on colorimetry (see Wyszecki and Stiles) nor a book on color reproduction (see Hunt), but a book on the subjective appearance of colors.
