1. A method for accurate and precise representation of color for at least one image, each image being represented by pixel values representing a plurality of color primaries, including the steps of: (a) measuring or determining spectral characteristics corresponding to at least one portion of at least one displayed image; (b) conveying or storing the color pixel values representing each displayed image plus the corresponding spectral characteristics of such image; and (c) applying the corresponding spectral characteristics of such image to transform the color pixel values prior to presentation display.
