Hmmm... Here's an old script I worked with when I was first learning
pygtk that should run under pygtk-0.6.4 and draws in a specified
color. Does it draw in dark slate gray when you run it? If so, try
and figure out what is different from your code.

r1 = int(random.uniform(10,100))
r2 = int(random.uniform(10,100))
fill = 1
cmap = widget.get_colormap()
# this is DarkSlateGray on a (255,255,255) color scale. I
# multiply by 255 to scale to the units of alloc, which are
# 0-65535 for each (R,G,B) value
color = cmap.alloc(49*255,79*255,79*255)

gc.foreground = color

fill, x, y,
r1, r2,
