Synaptic interactions to extract information about wavelength, and thus color, begin in the
vertebrate retina with three classes of light-sensitive cells: rod photoreceptors at low light …

Abstract concepts are relevant to a wide range of disciplines, including cognitive science,
linguistics, psychology, cognitive, social, and affective neuroscience, and philosophy. This …

The number of colors discernible by normal trichromats has been estimated for the idealized
object-color solid. How well these estimates apply to natural scenes is an open question, as …

We investigated the claims of EnChroma that their notch filters aid chromatic discrimination
in color-vision deficiencies (CVD). Few research studies have addressed these claims and …

Red-green colour vision deficiency (CVD) affects~ 4% of Caucasians. Notch filters exist to
simulate CVD when worn by colour vision normal (CVN) observers (simulation tools), or to …

Colours and emotions are associated in languages and traditions. Some of us may convey
sadness by saying feeling blue or by wearing black clothes at funerals. The first example is a …

This paper analyzes, through computational simulations, which spectral filters increase the
number of discernible colors (NODC) of subjects with normal color vision, as well as red …

Dichromacy impairs color vision and impoverishes the discrimination of surface colors in
natural scenes. Computational estimates based on hyperspectral imaging data from natural …

The claims made for 43 commercial filter 'aids', that they improve the colour discrimination of
red‐green colour defectives, are assessed for protanomaly and deuteranomaly by changes …

In natural scenes, visual discrimination of colored surfaces by individuals with X-linked
dichromacy is known to be only a little poorer than in normal trichromacy. This surprising …
