1. A method comprising employing a vocabulary of color names in assigning a color name to a pixel in a digital representation, including the steps of: providing said vocabulary of color names with a plurality of color prototypes, each said color prototype having a prototype color name and a corresponding prototype color value; comparing a pixel color value of said pixel to said prototype color value of each color prototype in the vocabulary, and obtaining a color match value for said each color prototype in the vocabulary; determining a closest color match value resulting from said step of comparing; and assigning to said pixel a particular prototype color name corresponding to said closest match value.
