I might have mentioned in passing that I've worked for 5 years in a pigment shop. It changed my life and changed my painting when I finally got around to cooking up my own watercolor paints. Being surrounded by 500+ colors did it. The KP catalog cover is from one of my color test sheets..it wasn't my idea. We have dozens of color charts like the one shown, hand-made in London, Darling, how else to show a gazillion colors?
These are just a few of the Cadmium pigments - 22 different colors. They come packed in 100 gram bags - yep Metric system. That's about 3.3 ounces. Why is it when I'm in Paris, I never have any trouble with the Metric system in a patisserie..hmmm
These are hand-blown glass mullers for mixing your paint up. You will not be grinding the pigment. They already did that at the mill in Germany. You'll just be integrating binder (linseed oil, egg tempera etc.) into the pigment. On the left is a pharmaceutical mortar and pestle. You can also get one in a kitchenware store. Don't tell.
P.S. For concerned readers, I made the pilgrimage to ROUSSILLON in '05 and wrote about it on PB in the May archives.
