The sapwood of African mahogany is clearly distinct from its heartwood and is a white or yellowish color. Freshly-cut santos mahogany heartwood is reddish brown in color.
While there is a slight variation in coloring between boards, there may be darker spots that resemble a deep red or purple. Honduran mahogany heartwood, however, varies in color. When freshly cut, it could resemble yellow, red, or pink, but darkens to a deep red or brown color as it ages. Exposure to sunlight for an extended period may cause fading in the color of the wood.
Because of this wide variety in color, other species of wood can often pass for mahogany. The grain patterns can also vary, either appearing straight or with waves. Irregularities in the grain may add to the aesthetic of the wood, producing blisters, stripes, roes, fiddlebacks, or a mottled appearance. Dark colored gum or white deposits may be present in pores, and the texture can range from fine to coarse.
