color space models and derivates

color space models and derivates (In French modèles colorimétriques et espaces colorimétriques dérivés) to extend the understanding of a color space, which is actually also a color space model, so-called derived color spaces must also be included in this discussion – specially prepared systems which can be traced back to the analysis color space CIEXYZ (device-independent) and the analysis and synthesis color space RGB (device-dependent) or the synthesis color space CMYK (device-dependent). Color spaces derived from CIEXYZ are CIExyY, CIELUV, CIELAB, and from these in turn CIELCH, HLS, HSV, HSB. R’G’B’J’ (elementary hues) and Kodak YCC are derived from RGB. CMYK and K (achromatic) are derived from CMY.
