Color science
Also called chromatics, it includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range or light.

Color science
colorimetry
Physics; Color science
The science of measuring color and color appearance. Classical colorimetry deals primarily with color matches rather than with color appearance as such. The main focus of colorimetry has been the ...
dorsal lateral geniculate nucleus (DLGN)
Physics; Color science
An area of the thalamus that serves as an important relay station for visual information on its way to the visual cortex. The dLGN (or LGN) is the primary target for outputs from retinal ganglion ...
hyperpolarization
Physics; Color science
An increase in the potential difference across the cell membrane of a neuron. Retinal photoreceptors differ from most other neurons in hyperpolarizing in response to stimuli.
tritanopia
Physics; Color science
Yellow-blue color blindness. Tritanopia is thought to result from the loss of function of the S-cones. Tritanopia is much less common than either protanopia or deuteranopia.
photopigment
Physics; Color science
Pigments in photoreceptors that change their conformation when they absorb a photon. The change in conformation of the photopigments in response to light is the first step in the process that leads ...
spectrally opponent
Physics; Color science
Neurons that are excited by one cone type and inhibited by another.
retina
Physics; Color science
The inside layer of the back of the eye that contains the photoreceptors and associated neurons. The earliest stages of visual processing take place in the neurons of the retina.
