The prehistoric Puebloan people to the northeast of the Hohokam area utilized turquoise, or "skystone," as a pigment. Crushed and mixed with other materials, it became a permanent paint. The Hohokam certainly had turquoise, because they made jewelry from it. They also had stone palettes for mixing pigments, as well as "paint pots" for storing either the raw minerals or the paint mixtures.
Ancient Mayans had another blue pigment material: the rare lapis lazuli, which yielded a deeper blue hue than turquoise. Did the Hohokam have access to this stone? There appear to be no sources in central Arizona, but they would have been able to trade with people in California or Colorado to attain lapis lazuli, as they did for saltwater shells.
I had my mother teach me to read when I was four, and I've never stopped. Now I can play with words all day long... it's the best job in the world.
