Proposed modification to the CAM16 colour appearance model to predict the simultaneous colour contrast effect

Abstract

Experiments were carried out to investigate the simultaneous colour contrast effect on a self-luminous display using colour matching method. The goals of this study were to accumulate a new visual dataset and to extend CAM16 to predict the simultaneous colour contrast effect. Five coloured targets together with a neutral grey were studied. A total of 132 test/background combinations were displayed on a calibrated display. Twenty normal colour vision observers performed colour matching in the experiment. In total, 2,640 matches were accumulated. The data were used to accurately model the lightness and hue contrast results. The model was also successfully tested using two independent datasets.
