Sienna is a shade of brown that has red-orange undertones. It is a rich, warm, earthy color that can vary in tone from yellowish brown to reddish brown. The name comes from the pigment made from the raw earth found around Siena, Italy, which has been used in art since ancient Roman times.
Definitions of Sienna
Here are some key definitions of the color sienna:
- A brownish-orange yellow. The color of the earth near Siena, Italy, which gives light sienna and raw sienna pigments.
- A medium to dark brown or yellowish-brown color that resembles the clay earth from Siena.
- A warm reddish brown color, sometimes with a slightly orange tinge.
Sienna sits between the colors of orange and brown on the color wheel. It is darker and contains more red undertones than basic orange, but is lighter and warmer than basic brown. When describing sienna shades, terms like reddish-brown, yellowish-brown, clay, orange-brown, and rust are commonly used.
The Origins of the Color Name Sienna
The name sienna derives from the Italian city of Siena, in Tuscany. The surrounding soil around Siena contains natural pigment minerals that create earthy brownish-red tones. During the Renaissance, artists began using the raw earth from Siena to create pigments for painting, referred to as terra di Siena in Italian. The English translation Sienna became the name for both the pigment and the reddish-brown hue it produced.
Sienna pigment has been around since ancient Roman times, but started being widely used during the Italian Renaissance in the 14th-16th centuries. Early Renaissance painters like Duccio and Botticelli used sienna for underpainting panels and frescoes. The Baroque period saw extensive use of sienna pigments in masterpieces by Rembrandt, Velázquez, and Caravaggio.
Types of Sienna Pigments
There are two main types of natural sienna pigment that painters have traditionally used:
- Raw Sienna – This is the natural iron oxide clay pigment that is extracted from the earth without any processing or heating. It produces a lighter, more yellowish brown.
- Burnt Sienna – The raw sienna clay is roasted at high temperatures to intensify the color and create a deeper, more reddish brown.
Today, most sienna pigments are synthetically produced rather than extracted directly from the earth. Modern sienna paint retains the color qualities of the original natural pigments with hues ranging from golden yellow browns to deep orange-browns with red undertones.
Sienna Color Meanings
Different shades of sienna evoke different meanings:
- Yellowish siennas signify warmth, earthiness, fall seasons, comfort
- Reddish siennas are associated with autumn, harvest, rust, fire
- Deep burnt siennas suggest maturity, weathered materials like leather or wood
Sienna is connected to the earth through its origin as an earthy pigment. It brings to mind images of clay, oxidized soils, autumn foliage and landscapes. Sienna shades are often described as “warm” – they seem to glow with undertones reminiscent of sunsets, baked earth, and flickering fires.

- In painting as an earth tone pigment for underpainting, landscapes, wood, rock, skin
