savefig problems

After a few trials and errors I could finally set up plots the way I wanted by
modifying the matplotlibrc resource. In an essence, I want bright information
(fonts,lines) on dark background (figure bg, axes bg) and I can fully achieve
this goal while DISPLAYING plots. However, SAVING damages their colors
ingloriously (I could not trace down the rule what is aimed to be achieved)
and tweaking the two options in the example matplotlibrc (savefig.facecolor
and savefig.edgecolor) would not help. In matlab there is a switch to disable
color inversion for hard copies: anything equivalent in the (otherwise
excelent) matlibplot?
Thanks a lot,
