The smooth orange theme, a recoloring of Xfce-smooth. Requires the xfce theme engine. This was designed to give an Orange look not dissimilar to the Wasp theme, which was removed from Ubuntu 8.10, but a bit more subtle. Looks great with the 'Tangerine' icon set (which is itself an orange recoloring of the blue 'Tango' icon set. Window border is Simplebox. Both Tangerine icons and engine are packages on ubuntu and debian. get gtk2-xfce-engines for the engine, which does not depend on any other xfce component.
