The effect of lighting changes on simultaneous colour contrast: a new aspect of colour rendition

Among the many metrics used to compute the colour rendition of a light source which have been investigated in recent years, most consider only the spectral power distribution of the light source being tested. To highlight aspects not usually considered in the development of colour rendition metrics, and to propose future directions for alternative approaches consistent with human visual perception, an experiment was conducted to examine colour appearance variations on certain spatial visual content configurations, in other words the effects of illusions under different light sources. Results indicate that stronger simultaneous contrast configurations have a more unpredictable variation in appearance. Therefore, it is proposed that colour spatial distribution should be considered for the future generation of rendering metrics.
