    matplotlib gives you 4 ways to specify colors,
    
        1) as a single letter string, ala MATLAB
    
        2) as an html style hex string or html color name
    
        3) as an R,G,B tuple, where R,G,B, range from 0-1
    
        4) as a string representing a floating point number
           from 0 to 1, corresponding to shades of gray.
