  How about:

    label = Label()
    r, g, b = root.winfo_rgb(label['background'])
    rgb = r / 256, g / 256, b / 256
    label.destroy()

  This should work under NT as well; testing this is a long way from
convenient for me here.  The disadvantage is the creation of an
intermediate widget, but a suitable existing widget is likely to be
available in real applications.
