1. A system for displaying a primary color system, comprising:
a set of image data including a set of primary color signals, wherein the set of primary color signals corresponds to a set of values in an International Commission on Illumination (CIE) Yu′v′ color space, wherein the set of values in the CIE Yu′v′ color space includes a luminance (Y) and two colorimetric coordinates (u′,v′);
an image data converter, wherein the image data converter includes a digital interface, and wherein the digital interface is operable to encode and decode the set of values in the CIE Yu′v′ color space; and
at least one non-linear function for processing the set of values in the CIE Yu′v′ color space;
wherein the decode includes rescaling of data related to a first scaled colorimetric coordinate and data related to a second scaled colorimetric coordinate;
wherein the rescaling includes multiplying the data related to the first scaled colorimetric coordinate by a first multiplier and multiplying the data related to the second colorimetric coordinate by a second multiplier, wherein the first multiplier is between about 1.42 and about 1.82, and wherein the second multiplier is between about 1.53 and about 1.89; and
wherein the encode and the decode includes transportation of processed Yu′v′ data, wherein the processed Yu′v′ data includes a first channel related to the luminance (Y), a second channel related to a first colorimetric coordinate (u′) of the two colorimetric coordinates (u′,v′), and a third channel related to a second colorimetric coordinate (v′) of the two colorimetric coordinates (u′,v′).
