Hi yesterday I was getting really frustrated using Paint shop Pro 9 to Colourise anyway with some googling I found this programme AKVIS Coloriage. You can download a 10 day free trial from here :-
You can use it stand alone or as a plug in to Paint Shop Pro 9 and others. I eventually found it worked best in PSP and you open your image in PSP and use Plug In in the Effects menu in PSP.
When I finally figured out how to use it I was amazed how quickly I did the following which was just an experiment. Not tried a face yet.
