“…9 and 10. This appears to be somewhat in conflict with the previous point that RT serves as an index of the ease level of the task, as a color displayed in very high luminance should decrease in the perception of saturation, 45 and it should thus become more difficult to determine its appropriate hue category. However, there are two possible reasons for the actual result.…”

This study presents the categorical formation of a set of Mandarin color terms on the International Commission on Illumination (CIE) 1931 chromaticity diagram across six luminance levels. This article conducted a study that employed 44 native Mandarin speakers to perform a force-choice sorting task. The Mandarin color terms for sorting were determined by a free-recall pretest and are consistent with basic color terms proposed by Berlin and Kay. The square-sampled stimuli were generated by evenly sweeping the x-y diagram of 5, 10, 25, 50, 100, and 170 cd/m 2 planes. The categorical sorting results and response time (RT) measurements suggest that: (1) the concepts of green, blue, purple, and gray stably exist at most luminance levels. The voting RT for the green, blue, and purple categories is particularly short. (2) Red, orange, yellow, and pink are highly luminancedependent; these can be identified without difficulty only at some restricted luminance levels. (3) The chromaticity areas designated as orange, partial yellow, red, and pink are recognized as brown when the luminance level decreases. (4) Brown and gray serve as representations of two distinct tints in the low saturation condition. (5) The location of boundaries between blue and green are remarkably different than those in a similar study that employed Japanese speakers.

Brightness perception of unrelated self-luminous colors

et al. 2013

The perception of brightness of unrelated self-luminous colored stimuli of the same luminance has been investigated. The Helmholtz-Kohlrausch (H-K) effect, i.e., an increase in brightness perception due to an increase in saturation, is clearly observed. This brightness perception is compared with the calculated brightness according to six existing vision models, color appearance models, and models based on the concept of equivalent luminance. Although these models included the H-K effect and half of them were developed to work with unrelated colors, none of the models seemed to be able to fully predict the perceived brightness. A tentative solution to increase the prediction accuracy of the color appearance model CAM97u, developed by Hunt, is presented.
