Individual differences in brightness matches between lights of different colors were determined for color-normal observers at both photopic and mesopic light levels using the method of flicker photometry. The standard deviations of the settings made by 52 observers at photopic levels did not exceed 0.1 log unit. Variability was greatest at the extremes of the spectrum. Variability was not appreciably increased at mesopic levels.
