Age-Related Effects on the Color Discrimination Threshold [PDF]
LifeTraditional color vision tests lack the sensitivity to detect subtle differences in individuals with normal color vision. The Konan ColorDx Cone Contrast Threshold (CCT) HD test allows the quantitative measurement of color discrimination thresholds for ...

Colors and Handles: How Action Primes Perception
Frontiers in Human Neuroscience, 2021 How deeply does action influence perception? Does action performance affect the perception of object features directly related to action only? Or does it concern also object features such as colors, which are not held to directly afford action?

Color Vision Improvement of Anomalous Trichromats Based on a Wide-Color-Gamut Display
IEEE Photonics Journal, 2022 Compared with normal color vision observers (NOs), anomalous trichromats (AT) have anomalous color vision responses owing to differences in cone sensitivity. The wide-color-gamut display provides a promising solution to this problem. Herein, we propose a

Wild hummingbirds discriminate nonspectral colors [PDF]
Proceedings of the National Academy of Sciences, 2020 Many animals have the potential to discriminate nonspectral colors. For humans, purple is the clearest example of a nonspectral color. It is perceived when two color cone types in the retina (blue and red) with nonadjacent spectral sensitivity curves are predominantly stimulated.
