color depth The possible range of colors that can be used in an image. There are
generally three choices with digital images: grayscale, 8-bit, and 16-bit. Higher color
depths provide a wider range of colors but require more storage space. See also
.
color interpolation The process of calculating additional color values from light
captured via the red, green, and blue elements on the digital image sensor.
color management system (CMS) An application that controls and interprets the
reproduction of color between devices and imaging software for accuracy.

.
color matching method (CMM) A software algorithm designed to translate color
information from one device profile to another, such as from your display to your printer.
ColorSync is a thoroughly integrated CMM used by Mac OS X. See also
.
Color Monochrome adjustment An adjustment in Aperture that desaturates the image
and applies a color tint of your choosing to the midtones. See also
,
.
color space A mathematical model used to describe part of the visible spectrum. Color
from one device is mapped from the device-dependent value to a device-independent
value in a color space. Once in an independent space, the color can be mapped to
another device-dependent space. See also
colorimeter An instrument capable of measuring the color value of a sample, using
color filters. A colorimeter is used to determine if two colors are the same. However, it
does not take into account the light under which a sample is measured. Colorimeters
are often used to calibrate displays and printers. See also
.
colorimetry The science of measuring color both objectively and perceptively.
ColorSync A color management system that is part of the Mac operating system. In
Mac OS X, ColorSync is thoroughly integrated with the entire operating system and is
available to all native Mac OS X applications. See also
ColorSync Utility A centralized application for setting preferences, viewing installed
profiles, assigning profiles to devices, and repairing profiles that do not conform to the
current ICC specification. See also
International Color Consortium (ICC)
.
color temperature Describes the color quality of light. Color temperature is measured
in units called kelvins (K). See also
.
Commission Internationale de l’Eclairage (CIE) An organization established in 1931 to
create standards for a series of color spaces representing the visible spectrum of light.
