ABSTRACT MATHEMATICAL MODELS USED IN COLOUR MANAGEMENT

Summary/Abstract: The colour space is an abstract mathematical model showing how colours can be represented. The colour systems in use are based on CIE (International Commission on Illumination) colour coordinates (RGB, CYM, CIELab, CIELuv, CMYK) and respectively on color assessment systems (Munsell, Hunter, Pantone or Trumach). The best known colour patterns are: RGB (Red, Green, Blue), CMYK (Cyan, Mangenta, Yellow, Black), HSV (Hue, Saturation, Value), HSL (Hue, Saturation, Lightness/Luminance). Modern colour analysis covers various colour spaces, e.g. HSL, HSI, HSB, CAT02LMS, as ways in which independent and dependent representations communicate and adapt to each other, laying the bases of the specific transfer matrix equation. Colour transfer between colour reception and rendering devices is conducted based on a selected mathematical model. A comparative analysis of various spatial representations is thus provided.
