Term: Color gamut
- Definition:
Color gamut is a subset or range of colors within the color space that can be reproduced on an output device. Monitors, projectors, and other image reproduction devices often have limitations to the colors they can accurately display, and the color gamut of a device defines the limitations.
Similarly to color spaces, color gamuts can be visualized as a shape that is overlaid on tape of the CIE 1931 color chart. Since a color gamut is a subset of a color space, meaning that a gamut can accurately reproduce less colors than are defined by its associated color space, the shape of the gamut will be slightly smaller than the shape of the color space.
Color gamut is limited by the parameters of the display device such as a monitor. For example, if a monitor is limited to Rec 709 display but the color gamut is set to another value, such as Rec 2020, the monitor can not accurately display the Rec 2020 color gamut so the intended color gamut may not be represented to the user.
