Color confusion

[William Ramsay <ramsayw1 comcast net>]

Hi,

I am working with both a pixbuf and a GtkDrawingArea, which I would like 
to have in sync.
The problem I am having is with matching colors between the two.   I use 
gdk_color_parse()
to get a GdkColor in both cases.   In the case of the pixbuf I use 
gdk_colormap_alloc_color
to get a pixel (using the system colormap).    I then fill the pixbuf 
with the resulting pixel
and modify the GtkDrawingArea background with the GdkColor.   The colors 
do not match.
My guess is that the colormaps don't match, but I have no idea how the 
get the colormap
the GtkDrawingArea is using.   And this may not be my problem.   Does 
anyone know how
can I get my colors to match?
