Towards a new colour appearance model for self-luminous stimuli

Based on the experimental visual data obtained for self-luminous stimuli surrounded by a dark background, a new colour appearance model (CAM) for unrelated self-luminous stimuli, CAM15u, was developed. The model can be a valuable tool to improve existing standards for traffic signs, LED billboards, etc. Furthermore, first experimental results about the assessment of the colour appearance of similar stimuli but surrounded by a luminous background are presented. This is considered as a first step to a general CAM for self-luminous stimuli.
