Color management

Color management uses device profiles and color-conversion methods to preserve intended colors as images move among cameras, displays, software, and print.

ICC profile: A standardized data file describing how a color device or color space represents color. Color management relies on profiles to characterize device behavior and define conversion endpoints.
CIE 1931 color space: A colorimetric system established by the International Commission on Illumination in 1931. Its standard observer and XYZ system anchor many device-independent color measurements.
Digital photography: Image capture and processing using electronic sensors and digital files. Camera profiles translate sensor responses into standardized color values.
Color correction: The adjustment of image colors to correct errors or achieve a desired appearance. Correction changes image appearance; management aims to preserve appearance across devices.
Color space: A mathematical model that assigns coordinates to colors within a defined range. Conversions depend on the source and destination spaces in which colors are encoded.
CIE XYZ: A device-independent color space based on standardized color-matching functions. XYZ values provide a common intermediate representation for profile conversions.
Display calibration: The adjustment of a display to meet specified color and luminance targets. Calibration makes a monitor's measured behavior more predictable for managed viewing.
Color grading: The deliberate shaping of an image's colors and tonal character for expressive or stylistic effect. Grading creates a look, while color management handles translation between color systems.
Color matching function: A set of functions describing how mixtures of three primaries match colors for a standard observer. Standard observer functions provide the perceptual basis for profile-based color measurements.
CIE Lab: A color space designed to approximate perceptual lightness and opponent color dimensions. Lab coordinates help express color differences and support perceptual conversion strategies.
