Comment(by jason):
This is great stuff.
Some initial comments:
# Lots of doctests are marked #random that shouldn't be (there should be
no #random doctests). Use ... to take care of memory addresses changing,
and use sort(dict.items()) to take care of things like dictionaries.
# .lighter() and .darker() seem to have too little contrast. Can we make
it so that they about double their steps? In other words, can we make it
so that .lighter() does what .lighter().lighter() does in this patch?
# Interestingly, colors.white.darker() gives gray values, but
colors.black.lighter() does not give gray values.
Of these the first is the real technical issue. Other things are fine-
tuning that can be put off to another patch.
