The other option would be to use the insert_text() method inherited from
the GtkEditable interface. It might work better for you.

A GdkColor represents a colour :). You can create colours with a
GdkColormap (such as the one returned by widget.get_colormap()). You just
call its alloc() method:
colour = cmap.alloc("red")
or:
colour = cmap.alloc(0xffff, 0, 0)
