The only thing drawn with fg color on a button is the focus
frame -- if it has focus.  But it should be visible, the
problem is that this, like the previous method and

    gtk_rc_parse_string("style \"fg-red\" {\n"
                        "  fg[NORMAL] = \"red\"\n"
                        "}\n"
                        "widget \"*.fg-red-button\" style \"fg-red\"\n");
    gtk_widget_set_name(button, "fg-red-button")

is defenceless against theme engines.  For example with
RedHat's bluecurve theme engine, it seems impossible to
change the color of the focus frame.  Without any theme
engine all methods work.
