A few colours were added "in-house" for the final image. I'd had a few cracks at it myself, but hated the sight of them, and gladly handed it over to be finished elsewhere. I still think the 'pure' one work better, to be honest. It's a bit classier, to my eyes. You have to be careful about adding yellow and brown to white... it can be somewhat suggestive of a bed of snow that someone's done their business in!
