ICC (International Color Consortium) Profiles describe the color attributes of a particular device or viewing requirement by defining a mapping between the source or target color space and a profile connection space (PCS). This PCS is either L*a*b* or CIE XYZ color space. Mappings may be done using tables, to which interpolation is applied, or through a series of parameters for transformations. The International Color Consortium was formed in 1993 by eight industry vendors in order to create a universal color management system that would function transparently across all operating systems and software packages. ...

Without further qualification, Lab color space refers to that of Hunter (Richard S Hunter, JOSA, 38, p 661 (1948)), which is an Adams Chromatic Valance Space. ...
The International Commission on Illumination (usually known as the CIE for its French-language name Commission Internationale de lEclairage) is the international authority on light, illumination, colour, and colour spaces. ...

In the mathematical subfield of numerical analysis, interpolation is a method of constructing new data points from a discrete set of known data points. ...
To see how this works in practice, suppose we have a particular RGB and CMYK color space, and want to convert from this RGB to that CMYK. The first step is to obtain the two ICC profiles concerned. To perform the conversion, each RGB triplet R,G,B is first converted to the PCS using the RGB profile. If necessary the PCS is converted between L*a*b* and CIE XYZ, a well defined transformation. Then the PCS is converted to the four values of C,M,Y,K required. REDIRECT RGB color model ...
Cyan, magenta, yellow, and key (black) CMYK (or sometimes YMCK) is a subtractive color model used in color printing. ...

A profile might define several mappings, according to rendering intent. These mappings allow a choice between closest possible color matching, and remapping the entire color range to allow for different gamuts. Rendering intent refers to the way the CMM (Color Management Module) will handle out of gamut colors during a conversion from one color space to another. ...
In color reproduction, including computer graphics and photography, the gamut, or color gamut (pronounced ), is a certain complete subset of colors. ...
Every device that captures or displays color will have its own profile. Some manufacturers provide profiles for their products, and there are several products that allow end users to generate their own color profile, typically through the use of a colorimeter. A colorimeter is a device used to measure the absorbance of a specific solution. ...
The International Color Consortium define the format precisely but do not define algorithms or processing details. This means there is room for variation between different applications and systems that work with ICC profiles. The International Color Consortium was formed in 1993 by eight industry vendors in order to create a universal color management system that would function transparently across all operating systems and software packages. ...
