1. A method of color enhancement using a detection volume and a shift volume, said method performed on a computing device, and comprising:

  • receiving color data for a plurality of pixels, color data for a pixel comprising a luminance value and a set of chromatic values;

    translating a set of chromatic values for a pixel into a first position in a color coordinate plane, said color coordinate plane corresponding to said luminance value;

    comparing said first position of said pixel to said detection volume;

    shifting said first position of said pixel to a second position if said first position is detected in said detection volume, said second position comprised in a shift volume, wherein said detection volume and said shift volume are variable along a luminance axis; and

    displaying said plurality of pixels.
