Colour gamut

The colour gamut (or simply: gamut) refers to the range of all colours in a colour space that can be recognised (camera, scanner) or reproduced (printer, monitor) by a device.
It is visualised in the form of a colour solid.

Colour location

The colour location describes the position of a measured or selected colour within a colour space. This is often defined by coordinates, e.g. using L, a and b in the CIELab colour space.
The set of all the colour locations in a colour space is called the colour gamut (or gamut).

Colour model

A colour model (or colour system) is an abstract mathematical method for determining and specifying colours and their relationship to each other.
It is sometimes referred to as colour space, although the latter is the concrete application of a colour model to a colour-producing method (printer, monitor, etc.).

Colour space

A colour space is based on a colour model, and is its concrete application to a colouring method (printer, monitor, etc). It therefore contains all colours that can actually be represented through this method and the associated materials.

Gamut

The gamut (also colour gamut) refers to the range of all colours in a colour space that can be recognised (camera, scanner) or reproduced (printer, monitor) by a device.
It is visualised in the form of a colour solid.

Gamut mapping

The conversion of colour values from one colour space (e.g. sRGB on the monitor) to another colour space (e.g. CMYK in print) so that the colour reproduction remains as consistent as possible.

sRGB

sRGB is the most widely used RGB colour space, and was created for monitors by Hewlett-Packard and Microsoft in 1996. sRGB is the standard colour space of all inexpensive digital cameras and scanners.
