  abstract =   "The paper presents novel techniques based on the Coloroid
               color system which hitherto has not been applied to gamut
               mapping. The introduced methods described are hue preserving
               and use three gravity centers in a hue-dependent way. Two of
               the gravity centers are shifted toward the direction of
               ‘negative saturation’, and can be used for regions of
               bright and dark colors, while a third gravity center is used
               for saturated colors.  After a short survey of gamut mapping
               an introduction to the Coloroid describes concisely its
               features and formulas. Then a simple color clipping rule is
               presented applicable to any rendering applications. A gamut
               mapping method will be defined mapping from a generic input
               image to an RGB display. Other variations of the method
               describe RGB-CYMK transformation and also cross-media
               mapping for known input and output gamut boundaries.  The
               introduced methods apply hue and chroma dependent lightness
               compression. They can be applied in realistic computer
               graphics and digital photography as well as in printing
               technologies. They are straightforward to implement and have
               low computational costs.",
