Colour rendering, referring to the impact of a light source on the colour appearance of objects, has been investigated for many decades. Several metrics, not all successful, have been proposed in an attempt to quantify the effect of the light source. The current standard method, the colour rendering index Ra developed by the International Commission on Illumination (CIE), offers an objective measure of the colour rendering properties of a light ...
