  From user's point of view if I looked for colors settings I would
look in applet settings, not in a theme.

  The network applet is unique among them because it uses graph with
two lines. I mean when you look at one line it does not matter which
color it is (well, people usually like when things are configurable,
but it's not _that_ important). But when there're two different lines
without proper colors it's hard to guess what's currently shown there.

  Also in case of network load red and green colors are widely spread
and different color may confuse people. At least it confuses me. :)

  As for me any suggestions are welcome.
