Glossary
Achromatic
–
Neutral in color (having no hue).
Additive Primaries
–
Red, green, and blue light that when combined in different relative inten-
sities produces different colors. (See also Subtractive Primaries)
Backlight
–
the internal light source for a Liquid Crystal Display, such as fluorescent lamps or
array of LEDs (Light Emitting Diodes).
Blackbody
–
A hypothetical object that absorbs all incident radiation, thus any radiation (e.g.
light) coming from a blackbody must be emitted from it and not reflected.
Blackbody Radiator Locus
–
The curved formed when the color of light radiated from a black-
body is plotted at different temperatures on a color space such as CIE xyY.
Black Level
–
The luminance or “brightness” of black when displayed on the screen.
Calibration
–
The process of bringing a device such as a display monitor to an absolute stan-
dard to ensure consistency over time and with other similarly calibrated devices.
Candelas (cd)
–
An international unit of light intensity. Luminance can be described in units of
Candelas per meter squared (cd/m
²
) but is often referred to as just Candelas or Nits for sake of
brevity.
CIE
– The Commission Internationale d’Eclairage (International Commission on Illumination).
An organization that sets many of the standards used in color and color measurement.
CIE Lab
– A color space that is relative to a reference white point. The L value represents light-
ness, a represents Red/Green and b represents Yellow/Blue. Lab is almost perceptually uni-
form in that differences between colors expressed in Lab correlate to equally perceived color
differences.
CIE uv chromaticity coordinates
– Coordinates in the CIE uv color space which are derived
directly from CIE xyY color space. CIE uv is more perceptually uniform than CIE xy.
CIE xy chromaticity coordinates
– Coordinates in the CIE xyY color space representing color
independent of luminance.
CIE xyY
– A standard color space in which the Y component represents luminance. The x and
y components represent color.
Color Gamut
– (See Gamut)
Colorimeter
– An optical measurement device used to measure color that responds to light by
separating it into red, green, and blue components.
Color Management System (CMS)
– Software used to control the handling of color between
scanner, monitor, and printer. ColorSync is an example of a CMS used on the Macintosh. Mi-
crosoft Image Color Management (ICM) is an example of a CMS used on Windows systems.
