I don't really see why the second one is better than the first. The
first has the advantage of being able to identify several different
palettes, one for each number-of-colors, while the second one it's
much harder to do that.

I apologize, I'm not sure what you mean by "import this and look at line
number four". To answer your questions:

- A named scheme (in colorbrewer) usually ranges from 3 to 10 
total-number-of-colors (I appended one in my last message).
- Fallback could be either done by the user or by PyX. It'd be nice
if PyX had a default fallback (and I would advocate if too few colors,
take the first n colors of the variant with the smallest number of
colors; if too many colors, do a gradient between the first and last
colors of the variant with the most colors), and that the user could
override the default if he/she chooses.
