Color science
quantum catch
Physics; Color science
The number of photons absorbed by the photopigment molecules of a photoreceptor. The rate of quantum catch in a photoreceptor determines its output.
luminance
Physics; Color science
The intensity (power weighted by the overallspectral sensitivity of the eye) per unit area of a light source.
unique hue
Physics; Color science
A hue that is perceptually unmixed, containing no other chromatic component. The four unique hues (red, green, yellow, and blue) are thought to be basic components out of which all other (binary) ...
Helson-Judd effect
Physics; Color science
The tendency of lighter achromatic surfaces to take on the hue of the illuminant under which they are viewed and darker achromatic surfaces to take on the complementary hue.
achromatic color
Physics; Color science
A neutral color such as black, white or grey (see chromatic).
color space
Physics; Color science
A system for ordering colors that respects the relationships of similarity among them. There are variety of different color spaces, but they are all three dimensional.
