[pstricks] pstricks and \ColoredOverlappedSurfaces

[Pedro Jorge Caridade]

Herbert
This is not a problem with prosper. At least at the first impression. I
have try the example in a simple pstricks example and the error is the
same. Since William define the color by the pstricks command 
\PassOptionsToPackage{dvipsnames}{pstricks}
is useless.

I suspect that the Denis example works only with the newrgbcolor
command. Since the pstricks now loads color or xcolor, the macros are
not prepared to evaluate the color present.

William, prosper load automatically the pstricks. You don't need to load
it again. Have a look in Hendri's HA-prosper to correct some bugs and to
add extra functionalities.
