Even though PMU has a chart, the panel area is a meter styled area so
gkrellmrc custom settings for text color and krell0/krell1 parameters
should use StyleMeter lines.  For example to change the text color:

StyleMeter pmu.textcolor wheat black shadow

Text size is locked into using the smallest font for now.

I'm sorry but the most theming features from gkrellm-pmu did't
survive in version 2.0. Nevertheless it uses theme defaults and
fits best in most themes. The following file is used when placed
in the current theme's pmu/ directory. Any normal image type can
be used. When not available, theme defaults are used.

battery       - the battery decal.  (see below)

--
The Battery Decal:
the battery image consists of 5 equally sized images aligned
vertically in one image. Each represents a battery capacity state.
The meanings from the top are:
no battery
empty battery
low battery
good battery
charging
AC
