• In this Letter, we propose a combined metric for quantifying the color discrimination capability of white light sources. This metric is based on considerations of human visual adaptation to daylight chromaticities, as well as on the concerns of the huge spectral diversity of modern light sources. Two existing metrics, S n e u t r a l (degree of neutrality) by Smet et al. [ Opt. Express 22 , 25830 ( 2014 ) OPEXFF 1094-4087 10.1364/OE.22.025830 ] and R d (hue transposition among color samples of the Farnsworth–Munsell 100 Hue color vision test) by Esposito and Houser [ Lighting Res. Technol. 51 , 5 ( 2019 ) LRTEA9 0024-3426 10.1177/1477153517729200 ] were adopted, and their weights were determined by a meta-analysis of five groups of psychophysical data on color discrimination. The superiority of the newly proposed metric was demonstrated by 16 groups of psychophysical data from eight color discrimination studies, as well as by a comparison with 29 typical color quality metrics and their linear combinations.
