RGB-CMYK

Using colors both on screen and on paper can be a very confusing. Especially CMYK specified colors pose problems, which is mainly due to the handling of the black component. Sometimes a program removes underlaying back components and sometimes the black component is added to the color ones. Some programs diplay equally distributed color components as gray, others mimick printers in showing them brown. The CMYK colors are shown in their original disguise as well as reduced to simple RGB components. A private version also shows HSB and Pantone Colors.
