We examined the performance of a gamut mapping algorithm in implementing a device profile for color management systems (CMS). To evaluate its performance, we focused on errors that would occur during transformation, using the device profile recording the gamut mapping.In order to have a mapping method that would be suitable for implementation, we developed a new gamut mapping algorithm which we call “Chroma Proportional Clipping (CPC)”. The algorithm we propose can preserve chroma and reproduce color tones while reducing errors through interpolation. The reproduction of chroma and tone was evaluated by subjective assessments, and the reduction of errors was evaluated based on color differences. In comparison with three conventional algorithms, CPC showed superior performance.
