To determine whether raw umber or burnt umber is better for underpainting, it’s important to consider their unique characteristics and the effect each can have on your artwork. Both pigments are popular choices for underpainting due to their fast-drying properties and versatility, but they offer different hues and undertones that can influence the final outcome of your painting.
What Is Underpainting and Why Is It Important?
Underpainting is an initial layer of paint applied to a canvas, serving as a base for subsequent layers. This technique helps to establish values, composition, and tonal contrast. It can significantly enhance the depth and richness of the final painting. Artists commonly use earth tones like raw and burnt umber for underpainting because they dry quickly and provide a neutral base.
Characteristics of Raw Umber and Burnt Umber
Understanding the properties of each pigment can help you decide which is best for your needs.
Raw Umber
- Color: Raw umber is a natural earth pigment with a cool, greenish-brown hue.
- Drying Time: It dries quickly, making it ideal for underpainting.
- Opacity: Generally more transparent, allowing for subtle layering.
- Undertone: Has a cooler undertone, which can affect the mood of your painting.
Burnt Umber
- Color: Burnt umber is a warmer, reddish-brown pigment obtained by heating raw umber.
- Drying Time: Also dries fast, suitable for quick layering.

Which Is Better for Underpainting?
The choice between raw umber and burnt umber ultimately depends on the desired effect and the specific needs of your artwork.
