“…CRI was designed as an indication of how natural or undistorted the light source makes the colour of objects subjected to it appear. The limitations and weaknesses of the standard CRI have been highlighted, demonstrating that this index is not suitable for estimating the visual characteristics of narrow-band light sources such as some types of fluorescent lamps or white LEDs [2][3][4][5][6][7].…”

“…The recent development of new light source technologies have revealed the limitations of CRI applicability [2][3][4][5][6][7], that is, the use of a normalised spectral power distribution, the necessity for a reference illuminant to compare the light source being tested, and the inadequacy of using a single number to summarize the several characteristics of the light source. To overcome potential confusion, a set of metrics presented as graphical information has been proposed to describe multiple properties, including average shifts in hue and chroma with respect to the reference light source [8].…”

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.
