A Colour Appearance Model based on Jzazbz Colour Space

Abstract

The current CIE colour appearance model CIECAM02 and its variant named CAM16 can well predict common colour appearance attributes including lightness, brightness, chroma, colowfulness, saturation, hue angle, and hue composition. These models are complicated as well as have mathematical problems. The current study aimed a new colour appearance model based on Jzazbz color space to obtain either better or similar performance compared with CAM16 but the new model should be computationally simple and robust. Such a model will particularly be suitable for color management in high dynamic range and wide color gamut applications. A range of experimental data were collected and a set of equations was derived. Some initial test results are presented in this paper.
