Abstract
High-fidelity color image reproduction is one of the key issues in visual telecommunication systems, for electronic commerce, telemedicine, digital museum and so on. All colorimetric standards of display systems are up to the present day trichromatic. But, from the shape of a horseshoe-area of all existing colors in the CIE xy chromaticity diagram it follows that with three real reproductive lights, the stated area in the CIE xy chromaticity diagram cannot be overlaid. The expansion of the color gamut of a display device is possible in a few ways. In this paper, the way of increasing the number of primaries is studied. The fourth cyan primary is added to three conventional ones to enlarge the color gamut of reproduction towards cyans and yellow-oranges. The original method of color management for this new display unit is introduced. In addition, the color gamut of the designed additive-based display is successfully compared with the color gamut of a modern subtractive-based system. A display with more than three primary colors is called a multiprimary color display. The very advantageous property of such display is the possibility to display metameric colors.
