Change Request

rcsetup.defaultParams uses the single-letter shorthands for color definitions. This leads to definitions like these:

    'text.color':          ['k', validate_color],     # black
    'axes.facecolor':        ['w', validate_color],  # background color; white

I propose to exchange them for the long color names 'black' and 'white' for better readability.

Is there something to be aware of when changing the string without changing the semantics or can I simply replace them?
