Burnt umber is a deep, rich brown pigment with warm, reddish-brown undertones. Its unique hue comes from its composition and the process used to create it. Unlike raw umber, which is a naturally occurring earth pigment, burnt umber is made by heating raw umber. This heating process, known as calcination, alters the pigment's chemical structure, resulting in its characteristic dark brown color.
The exact shade of burnt umber can vary slightly depending on the source of the raw umber and the length of the heating process. However, it generally falls within a range of dark reddish-browns, often described as a warm, earthy tone. This versatility makes it a popular choice for artists and designers across various mediums.
What is Raw Umber and How Does it Differ from Burnt Umber?
Raw umber is a naturally occurring earth pigment containing iron oxides and manganese oxides. It's typically a yellowish-brown color. The key difference between raw and burnt umber lies in the heat treatment. Heating raw umber changes its chemical composition, darkening the pigment and shifting its color towards a deeper, reddish-brown – resulting in burnt umber. Raw umber has a lighter, more yellow-toned brown hue compared to burnt umber's richer, darker, and more reddish-brown shade.
What are the Uses of Burnt Umber?
Burnt umber's versatility makes it suitable for numerous applications:
- Painting: It's a popular choice for artists working in oils, acrylics, and watercolors. Its rich tone is ideal for creating shadows, depth, and underpainting. Its warm undertones blend beautifully with other colors.
- Drawing: Burnt umber is frequently used in pencils, pastels, and charcoal for its intense color and blending capabilities.
- Interior Design: Burnt umber is a popular color choice for paints, fabrics, and furniture due to its earthy and sophisticated appeal. It evokes feelings of warmth and comfort.
- Cosmetics: Burnt umber can be found in eyeshadows, bronzers, and other makeup products, providing a natural-looking, warm brown tone.
What Colors Can Be Made Using Burnt Umber?
Burnt umber, while a rich brown on its own, can be used to create a surprising range of colors when mixed with others:
- Mixing with white: Creates a range of lighter browns, from light beige to taupe.
- Mixing with black: Produces darker, more intense browns and even muddy dark tones.

- Mixing with red: Produces deeper, richer browns with reddish hues.
- Mixing with blue: Creates muted greens and gray-browns.
How is Burnt Umber Made?
As mentioned, burnt umber is made by heating raw umber. The raw material is heated to a high temperature, which causes a chemical change, converting the yellowish-brown raw umber into the darker, reddish-brown burnt umber. The precise temperature and duration of heating will influence the final color.
Is Burnt Umber Toxic?
Burnt umber, as a naturally occurring earth pigment, is generally considered non-toxic. However, like any art material, it’s essential to practice good hygiene. Avoid ingestion and ensure proper ventilation when working with it, especially in powdered form.
What is the Hex Code for Burnt Umber?
There isn't a single definitive hex code for burnt umber as its shade can vary slightly depending on the manufacturer and pigment source.

The best way to determine the exact hex code is to use a color picker tool on a specific burnt umber pigment you are working with.
This comprehensive overview should provide a detailed understanding of burnt umber color and its many uses. Remember that the nuances of color are subjective, and perception can vary. Experimentation is key to fully appreciating the depth and versatility of this rich pigment.
