[pygtk] Colors in calendar

[Kosa]

Hello list,

I'm really loving python and pygtk, but I asure
you I ask just thi things I can't find the way
to do after several days.

This is my question this time:
is there any way I can set colors to the gtk.Calendar()
widget?

I mean, background color, marked day color (besides the
default bold mark), perhaps change the "selected-day"
color.

Thanks in advance.

Kosa
