When I was a kid, my favorite crayon was the one called "Burnt
Sienna." It produced a warm orange-brown color that reminded me
of Georgia Red Clay. I wasn't far off the mark. The rich
pigments of the color sienna are derived from a form of limonite
clay used in the production of oil-based paints. Ferric oxides
found in certain soils produce the complex color. Natural soil
pigments, such as siena, ochre and umbra are found in many cave
paintings and are believed to be the first pigments used by
humans. Burnt sienna is a warm reddish-brown hue, created by
heating raw sienna to remove excess water from the clay.
"Sienna" is short for Terra di Siena, or "earth of Siena." The
color is named for the town of Siena, ITALY, where it occurs in
abundance. The southwest entrance to Siena through medieval city
