What does sienna mean?
Sienna is a warm reddish-brown colour, ranging from a muted yellowish brown to a deeper russet-like shade, and it is also the name of a natural earth pigment made from clay. In its colour sense, the word often appears in combinations such as “sienna brown,” “raw sienna,” and “burnt sienna.” Artists have long valued the pigment because it produces earthy, warm tones and can be combined with other colours in drawing and painting. The term is especially associated with Renaissance and later academic art, where mixtures of sienna and related earth colours were common. Its name comes from Siena, the Italian city traditionally associated with the source of the pigment. Sienna should not be confused with sepia, another brownish artist’s material, or with Siena itself, the place name. In ordinary modern use, it usually refers to the colour, while “raw sienna” and “burnt sienna” more specifically identify pigments.

Where does sienna come from?
The English word comes from Italian sienna, meaning “Sienna brown” or “earth of Siena,” and refers to the warm reddish-brown colour and pigment historically obtained from the region around Siena in Tuscany. The place-name Siena is therefore the source of the colour's name. Its associated English forms include the geographical and cultural terms Sienese and the less common senese.
