Colour
Colour (Medicine)
Colour (pronounced: /ˈkʌl.ər/) in medicine refers to the visual perceptual property corresponding in humans to the categories called red, green, blue, and others. Colour derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. The science of colour is sometimes called chromatics, colorimetry, or simply colour science.
Etymology
The word "colour" comes from the Old French couleur, which derived from Latin color. The first recorded use of colour as a noun in English was in the year 1300.
