Is mahogany more red than brown?

Mahogany is a classic wood known for its rich, red-brown color and elegant grain patterns. But is this wood actually more red or more brown? The answer lies in the unique color chemistry of mahogany.

The Color Chemistry of Mahogany

The distinctive color of mahogany comes from its mix of pigments. Mahogany contains reddish pigments called anthraquinones as well as brownish pigments called tannins. The concentration and balance of these two pigment groups help create the depth and variation in mahogany’s color.

Anthraquinones are red organic compounds found in the heartwood of mahogany trees. As a mahogany tree grows, it produces anthraquinones to protect its interior wood from fungi and insects. Higher concentrations of anthraquinones make the wood more red, while lower amounts lead to a more brownish mahogany.

Tannins are brown polyphenolic compounds also made by the mahogany tree. Tannins act as natural pesticides and give mahogany its characteristically warm, brown undertones. Mahogany trees with higher tannin content will produce wood that appears more brown than red.

Examining Mahogany’s Color Variations

There are over 200 species of mahogany growing across the Americas, Africa, and Asia. While all mahogany has the signature mix of red and brown, some types display more red hues while others lean brown.

For example, Cuban mahogany has very high concentrations of anthraquinones, giving it a distinctive reddish color. Honduran and African mahogany have lower anthraquinone levels, making their wood appear more brownish-red. Even within a single mahogany species, color can range from cinnamon brown to deep red depending on growing conditions and individual trees.

Redness Rating of Various Mahogany Species

Mahogany Species Redness Rating*
Cuban Mahogany 8/10
Honduran Mahogany 6/10
African Mahogany 5/10
Philippine Mahogany 7/10

*Higher scores indicate more reddish color

This table shows the relative redness ratings for several common mahogany species. Cuban mahogany is the most red, while African mahogany generally appears more brownish. Yet even within these broad categories, individual boards may be more red or brown.

Measuring Mahogany’s Color Scientifically

The most objective way to assess mahogany’s color is through scientific measurement. Wood scientists use spectrocolorimeters and other instruments to analyze the wavelength and intensity of light reflected from a wood sample. This data generates numerical values for variables like hue, lightness, and chroma.

For example, a deeply red Cuban mahogany board may have a hue angle of 25° in the red-yellow color spectrum. It would also have high chroma, indicating richer color saturation. A browner African mahogany sample could have a hue angle of 40° into the red-orange spectrum and lower chroma.

By comparing many mahogany samples, researchers can say whether a species overall appears more red or brown. However, there is still considerable variation between individual boards. Some Honduran mahogany with high anthraquinone content may test redder than lower-anthraquinone African mahogany.

Average Hue Angle and Chroma Values for Mahogany Species

Species Hue Angle* Chroma Value**
Cuban 22° 18
Honduran 32° 14
African 38° 12

*Lower hue angles indicate more redness

**Higher chroma values mean more color saturation

These numbers confirm Cuban mahogany is generally redder, with a hue closer to pure red and higher color saturation. But mahogany selection should still be based on each individual board.

Evaluating Individual Mahogany Boards

Ultimately, the question of whether a given mahogany is more red or brown depends on each unique board. Only by examining the wood firsthand can its specific color be determined.

Here are some tips for picking the reddest or brownest mahogany board possible:

  • Inspect boards in natural daylight for accurate color
  • Focus on heartwood, avoiding lighter sapwood
  • Look for rich, saturated colors
  • Compare board colors side-by-side
  • Ask to see more boards to select the hue you want

With attention to detail, you can find mahogany that suits your project’s needs. Some boards will appear distinctly red, while others read as more brownish. Your personal color preferences should guide you in choosing the perfect mahogany.

Factors That Impact Mahogany Color

Many variables beyond wood species affect mahogany’s final color, including:

Growing Conditions

The climate, soil chemistry, and geography where a mahogany tree grows impacts its heartwood pigments. Cooler highland areas often produce redder mahogany. The same species from a wet, lowland forest may yield browner wood.

Age of the Tree

Older mahogany trees have more time to accumulate anthraquinones, leading to redder heartwood. Younger trees usually have less red pigmentation.

Processing and Cutting

How mahogany is cut and processed after harvesting alters its color. Kiln drying can enhance redness, while air drying retains more brown tones. Quarter-sawn boards often appear redder than flat-sawn planks from the same log.

Finish and Stain

The final finish profoundly impacts how red or brown mahogany looks. Clear finishes allow the wood’s natural color to show. Reddish stains make it appear more red, while brown stains shift it toward brown.

Is Mahogany’s Color Stable Over Time?

Like many woods, mahogany’s color changes slightly after cutting and finishing. Initially, fresh mahogany may appear more reddish. As the wood ages and oxidizes, it generally becomes browner and richer in tone.

This mellowing effect is part of mahogany’s charm. Woodworkers may deliberately age new mahogany using chemical solutions to hasten the development of its mature, brownish-red patina.

With exposure to sunlight, mahogany also deepens in color over decades. Light causes chemical changes in the wood cells, slowly making the color more Brown with a reddish cast.

Does Mahogany’s Color Fade with UV Exposure?

While sunlight makes mahogany subtly redder and browner, UV rays can degrade the wood’s color if exposure is extensive. Fading is a particular risk for unfinished mahogany outdoors.

When wood is left exposed to the sun’s UV radiation without a protective finish, its lignin breaks down. This leads to bleaching of mahogany’s red and brown pigments, leaving the wood pale and washed-out.

However, mahogany colored by a non-transparent stain or solid opaque finish has much better UV resistance. The pigments in these finishes help block light from degrading the wood. This prevents color loss while allowing mahogany’s tone to gracefully age and mellow over time.

Choosing Between Red and Brown Mahogany

Mahogany with a more reddish or brownish cast has unique beauty. On large projects with many boards, combine both red-leaning and brown-leaning mahogany for lively, natural-looking color variation.

For smaller objects or furniture pieces, think about the overall look you hope to achieve:

  • Redder mahogany provides a bold, warm look and intricately shows off grain
  • Browner mahogany has a more relaxed, casual effect with softer grain patterns

Your personal taste should guide you in selecting mahogany that has the perfect balance of red and brown tones for each project.


While mahogany has signature red and brown tones, its exact color depends on the species, growing conditions, and individual board. By understanding what makes this classic wood more red or brown, you can pick the right mahogany for your needs. Whether you prefer the wood’s redness or brownness, mahogany’s complexity and elegance will enhance any application.
