Researchers and designers who work with color displays often confronts with the color gamut transform between different display devices. However

there are still deviations in the transformed gamut for other factors. This paper demonstrates the principle in the color transformation and the way the color transformed enveloped is plotted when quantization form is present. Simultaneously

the analysis of error on three-dimensional representation of the color gamut has been given. This paper demonstrates the effect of quantization error on the transformation based on analyzing the color gamut deviation profoundly. The conclusion can be utilized to appraise the quality of the color gamut transformation and can tell whether it is possible to obtain a color of a given chromaticity at a required display panel. Such interdependencies are easily recognized when full three-dimensional representations are available.
