COLOR MODEL

One method for outlining a color model is to specify a collection of two or more primary colors that are combined to provide various other colors. Common color models defined with three primary colors are the RGB and CMY models. Video monitor displays use the RGB model, while hardcopy devices produce color out- put using the CMY model. Other color models, supported specification of luminance and purity values, include the YIQ, HSV, and HLS color models. Intuitive color models, like the HSV and HLS models, allow colors to be specified by selecting a worth for hue and also the amounts of white and black to be added to the chosen hue.
