# changing page color


I use the following options to the preview version of texpower

\usepackage[sans,coloremph,colorhighlight,lightbackground]{texpower}

Is it possible to change the pagecolor for the whole document without
modifying tpcolors.cfg?  If I put a \pagecolor{..} just before or after
the \begin{document}, it has no effect.  If I put it in each slide
environment, it works, but it's "overkill".

Thanks

Stefan
