Salience of unique hues and implications for color theory.
The unique hues--blue, green, yellow, red--form the fundamental dimensions of opponent-color theories, are considered universal across languages, and provide useful mental representations for structuring color percepts. However, there is no neural evidence for them from neurophysiology or low-level psychophysics. Tapping a higher prelinguistic perceptual level, we tested whether unique hues are...
متن کاملUnique Hues
One can see so many different colors in the environment. And yet there are only four colors that occupy a special place in color perception. They are called unique hues and they originate from the opponent colors theory proposed by Ewald Hering in 1878 [1, 2]. The theory postulates three opponent processes: two chromatic processes of red-green and blue-yellow and one achromatic process of white...
متن کاملVariations in normal color vision. II. Unique hues.
We examined individual differences in the color appearance of nonspectral lights and asked how they might be related to individual differences in sensitivity to chromatic stimuli. Observers set unique hues for moderately saturated equiluminant stimuli by varying their hue angle within a plane defined by the LvsM and SvsLM cone-opponent axes that are thought to characterize early postreceptoral ...

p = 0.38, respectively). Moreover, analyses of only high confidence states yielded similar results as when highand lowconfidence states were pooled (see Supplemental Data). Together with the numerically large and robust difference between expected and unexpected percepts in the test phase, these observations speak to a true perceptual bias rather than a mere response bias. Our work shows that e...
متن کاملEmpirical evidence for unique hues?
Red, green, blue, yellow, and white have been distinguished from other hues as unique. We present results from two experiments that undermine existing behavioral evidence to separate the unique hues from other colors. In Experiment 1 we used hue scaling, which has often been used to support the existence of unique hues, but has never been attempted with a set of non-unique primaries. Subjects w...
