Review of measures for light-source color rendition and considerations for a two-measure system for characterizing color rendition
Twenty-two measures of color rendition have been reviewed and summarized. Each
measure was computed for 401 illuminants comprising incandescent, light-emitting diode …

Human perceptions of colour rendition vary with average fidelity, average gamut, and gamut shape
An experiment was conducted to evaluate how subjective impressions of a light source's
colour quality depend upon the details of the shifts it causes in the colour appearance of …
