Modelling Incomplete Chromatic Adaptation and Colour Contrast Using Memory Colours

The chromatic adaptation and colour contrast cause the colour appearance shift according to the adapting illuminant and background, respectively. It is difficult to distinguish between these effects because they all have an impact on the colour appearance of objects. . An experiment was conducted using memory colour matching approach in real scene at a high luminance level of various sources on the blackbody locus and some saturated colours. The results were used to develop two kinds of models for the incomplete adaptation factor (D) in CAT02. The necessity of a target dependent correction was discussedstatus: accepte
