Color science
principle of univariance
Physics; Color science
The fact that the effect on a photopigment of absorbing a photon is independent of its wavelength. Thus the response of a photoreceptor is determined solely by the number of photons absorbed and is ...
Hue
Physics; Color science
The quality of colours that is described by words such as red, yellow. Hue is determined by the wavelength of the color.
Rainbow
Physics; Color science
An arc of colours that sometimes appears in the sky, usually after it rains. Rainbows appear when light from the Sun hits droplets of water.
Prism
Physics; Color science
A transparent object that breaks up the light passing through it into a spectrum of colors. A prism has triangular ends.
Infrared light
Physics; Color science
Electromagnetic radiation that is invisible and has wavelengths that are longer than those of visible light.
Colour
Physics; Color science
The way light of a particular wavelength appears to the eye. The human eye sees light with long wavelengths as red or orange.
Color-blind
Physics; Color science
Unable to see the difference between certain colors. People who are colour blind usually cannot tell red from green.
