Color science

S-cone

Physics; Color science

One of the three cone types that contribute to human color vision. The peak spectral sensitivity of the S-cones is at a shorter wavelength than that of the other two cone types, the L-cones and ...

chromatic response function

Physics; Color science

A function from the wavelength of a stimulus to an aspect of its perceived color. For example, the yellow-blue process of opponent process theory is characterized by a function from the wavelength ...

agraphia

Physics; Color science

An impairment in the ability to write.

isomerization

Physics; Color science

The change in conformation upon absorption of a photon that the chromophores in photopigments undergo.

hue coefficient

Physics; Color science

The ratio between the response in one of the chromatic channels to the total chromatic response. A stimulus that is seen as equally bluish and reddish would for example have a hue coefficient of . 5 ...

additive mixture

Physics; Color science

A mixture in which the light from each of the components reaches the eye in an unmodified state. Lights superimposed on a projection screen are an example of an additive mixture. (See subtractive ...

visual cortex

Physics; Color science

Those cortical areas primarily concerned with the processing of visual information. The visual areas of the cortex are primarily located in the occipital lobe: the rear, lower part of the cortex.
