Hmmm...
I would actually NOT recommend starting with The Colour of Magic. My justification for this is that it's the only one I've read, and it just didn't do anything for me. I've said this to many Terry Pratchett fans and they have all, to a man (or woman), said "Well, it's actually not particularly good compared to the later ones. Perhaps you should try one of the others." Small Gods certainly came up as a recommendation.
I've never got round to trying one of the others. Perhaps I will now.
