Why you don't just create the pixbufs and fill them with the
required color (which can be done with gdk_pixbuf_fill() or
with Cairo if you want more complex drawing), and go through
pixmaps that use server-side resource... instead?

It's also possible to create just one pixbuf and fill it
with the corresponding color in the cell data function of
the tree view.
