One reasonable way would be to calculate the mean color of the image. Then calculate the delta E (color difference) from every pixel to that mean color. Then histogram the delta E image. See http://www.mathworks.com/matlabcentral/fileexchange/31118-color-segmentation-by-delta-e-color-difference
Or you might want to calculate the Color Frequency Image
