First you need to define what differentiates one color from another. Where exactly does "red" end and "purple" begin?

Here's some interesting info from a comment of mine to a different post a few days ago:
Pick your color values from one of these web sites:
http://ivrg.epfl.ch/files/content/sites/ivrg/files/research/alindner/CIC2012/www/ColorThesaurus.html Type blue-grey (using the UK spelling of gray) into the search field. You can type any color in any language in and get the color. Or, pick a color from a color picker and find out the names in 9 or 10 different languages for that color.

Take a look at the "color frequency image" in this link: http://www.mathworks.com/matlabcentral/fileexchange/28164-color-frequency-image You can probably adapt the code to handle different bin sizes. You question is exactly what the color frequency image is designed for. If you have any questions about how it operates, ask me - I understand the concepts in it.
