Gamut mapping algorithms, implemented by color management systems, are an integral part of the color reproduction process. By adjusting the colors with appropriate algorithms, gamut mapping enables original colors to ‘fit’ inside differently shaped color gamuts and authentically transfers images across a range of media.
This book illustrates the range of possible gamut mapping strategies for cross-media color reproduction, evaluates the performance of various options and advises on designing new, improved solutions. Starting with overviews of color science, reproduction and management, the text includes:
- a detailed survey of 90+ gamut mapping algorithms covering color-by-color reduction and expansion, spatial reduction, spectral reduction and gamut mapping for niche applications;
- a step-by-step example of a color’s journey from original to reproduction, via a digital workflow;
- a detailed analysis of color gamut computation, including a comparison of alternative techniques and an illustration of the gamuts of salient color sets and media;
- a presentation of both measurement-based and psychovisual evaluation of individual color reproductions;
- an overview of alternative approaches to gamut mapping proposed by the ISO and the CIE including an analysis of the building blocks of gamut mapping algorithms and the factors affecting their performance.
Color Gamut Mapping is a comprehensive resource for practicing color and imaging engineers, scientists and researchers working in the development of imaging devices, software and solutions. It is also a valuable reference for students of color and imaging science, as well as photographers, graphic designers and artists.

Ján Morovi is currently a Senior Color Scientist at Hewlett-Packard Espanola, Barcelona, Spain. He is highly regarded in the field of colour science, being Chair of the CIE (International Commission on Illumination) technical committee 8-03 on gamut mapping, a post he has held since 1998. Before his appointment in industry for Hewlett-Packard, Dr Morovi has also had academic experience at the University of Derby, UK. He has delivered lectures to an international audience, both academic and industrial, led industrially funded projects, and developed new commercial technologies. In addition, he has authored 62 academic publications, including book chapters, journal, and conference papers on colour gamut mapping, and also helped to create a CIE technical report detailing guidelines for the Evaluation of Mapping Algorithms.
