The change in conformation upon absorption of a photon that the chromophores in photopigments undergo.
Industry:Physics
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 for both red and blue while the unique hues all have coefficients of 1. 0 for one channel and zero for the others.
Industry:Physics
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 mixture)
Industry:Physics
Location in a chromaticity diagram. Chromaticity is often used as a convenient approximation to chromaticness, which is the hue and saturation of a color ignoring brightness.
Industry:Physics
Coordinates that specify position in a chromaticity diagram. The chromaticity coordinates of a stimulus are derived from its tristimulus values by taking the ratio of each of the tristimulus values to their sum; i.e. x=X/X+Y+Z, y=Y/X+Y+Z, where x and y are the chromaticity coordinates and X,Y, and Z the tristimulus values.
Industry:Physics
Attribute of visual sensation which has given rise to color names such as: blue, green, yellow, red, purple, etc. (CIE 45-25-215. ) Hue differences depend primarily on variations in the wavelength of light reaching the eye. One of the three standard elements of color appearance (the other two are brightness and saturation). Its colorimetric equivalent is dominant wavelength.
Industry:Physics
One of the two varieties of red-green color blindness (also known as red-dichromacy). Protanopia is thought to result from the loss of function of the L-cones. Protanopes display a marked loss of sensitivity to light at the long wavelength end of the spectrum. (See deuteranopia. )
Industry:Physics
A hue. All colors other than the neutral colors white, black, and the pure greys, are chromatic. The word "color" in ordinary language is often used to refer exclusively to chromatic colors, e.g., color vs. black-and-white television.
