- Abstract: We report color-appearance-matched data under high-dynamic-range luminance conditions. Theexperimental method and apparatus proposed in a previous study (J. Hwang et al., J. Opt. Soc. Am. A, 36 1940 (2019))were used to measure perceptual color shifts in the R, G, B, Y, RB, BG, GY, and YR groups of 16 samples under fourdual-illumination conditions at luminance levels of (300 cd/m2 and 4,500 cd/m2), (20 cd/m2 and 300 cd/m2), (80 cd/m2and 4,500 cd/m2), and (20 cd/m2 and 4,500 cd/m2). We observed a decrease in lightness for all samples, and hue shiftstoward blue in R, red in reddish YR, and green in BG samples when the luminance changed from low to high.Correlated changes in lightness and chroma, that is, an increase in lightness change and a decrease in chroma changeunder the highest luminance contrast (20 cd/m2 and 4,500 cd/m2), were observed for the Y, GY, and YR samples.
