We show that the thresholds depend on the spectral responsivities of each observer. We also analyze the influence of luminance level on the thresholds: a strong inter-observer variability is found at low or moderate luminance levels (0.02 < Y < 1 ft-L) whereas at high intensities (1 < Y < 7 ft-L) the thresholds are observer-independent.engjournal articlehttp://dx.doi.org/10.1002/col.20259http://onlinelibrary.wiley.com/doi/10.1002/col.20259/fullrestricted access535-2535.6535.3Color visionLuminance thresholdsVariability of color-matching functionsInter-observerÓptica (Física)Color2209.19 Óptica Física2209.03 colorimetría
