Probably you theme - your test program works fine for me in the
default theme, but Red Hat's "Bluecurve" theme ignores the
progress bar color from the theme - I think it uses a pixmap.
Other theme engines may do similar things.
If you want to ignore the theme for the widget, an old fashioned:
style = gtk_style_new ();
gdk_color_parse ("red", &style->bg[GTK_STATE_PRELIGHT]);
gtk_widget_set_style (widget, style);
g_object_unref (style);
Should do it. Standard disclaimers about the affects on consistency
and accessibility of ignoring the theme and of setting your own
colors.
