Spectral color reproduction using a high-dimension reflective display

An apparatus for color reproduction in a display device, comprising:

• means for receiving spectral color input to be displayed on the display device;
• means for selecting a primary from a plurality of available primaries that is a closest match of a spectral reflectance of the spectral color input, wherein each of the plurality of available primaries has an associated spectral reflectance;
• means for displaying the selected primary in a temporal frame of a set of temporal frames for a pixel and passing to a next temporal frame of the set of temporal frames, one or more spectral errors between the spectral reflectance of the selected primary of the temporal frame and the spectral reflectance of the spectral color input;
• means for repeating passing the one or more spectral errors to a next temporal frame until all temporal frames of the set of temporal frames for the pixel are used;
• and
• means for passing remaining spectral errors to neighbor pixels for spatial error diffusion at each spectral band after all temporal frames of the set of temporal frames for the pixel are used.
