The city that named a colour
Siena
A Tuscan hill city of warm brown brick, and the source of the earth pigment called sienna.

Why Siena is burnt sienna
Siena, in Tuscany, gave its name to a pigment. The earth of the region is rich in iron oxide and was dug and sold to painters as terra di Siena. Used as it comes, it is a yellowish brown called raw sienna. Roasted, it turns a warm reddish brown, burnt sienna. Both were standard colours for artists for centuries. The city itself is the same range: brick walls, brick towers and the shell-shaped Piazza del Campo, paved in red brick. The cathedral adds bold stripes of white and very dark green marble. Twice each summer the Palio horse race fills the square with the flags of the city districts, each with its own colours.
Values are fair approximations of what the eye sees there, not measurements.
