Excellent stuff Kevin. I hear the Germans like a nice watercoloured section as well. However, why not just cut out the middle man and smear a load of the mud on your context sheet? I suppose it might mean a less aesthetically pleasing archive. Munsell sheets might not be perfect, but they are cheaper than spectroscopy and might cut down on the kind of pointless quibbling that gorilla describes.
