There are two ways to repaint it. If you follow the way @sambob_12 suggested, it is fairly temperamental as the template is very rarely set up ready to use.
Before you start repainting, you need to make sure that you have the windows, destination display and anything that should not be repainted, copied onto a third layer ontop. Otherwise it will paint over them and be left with nasty results.
Also, @sambob_12, please don't begin to start presuming that this method applies for all templates. In fact, very few templates work in this way
