Trustworthy Mahogany

#915b1b
Notes

Trustworthy Mahogany (#915B1B) is a deep orange with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (33°, 69%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Mahogany
noun

The genus Swietenia — particularly S. macrophylla, the South and Central American hardwood prized since the eighteenth century for furniture and ship building. The color refers to a freshly polished Honduras mahogany table: a deep, slightly red-shifted dark brown with the satin finish of high-density tropical hardwood.
