Calm Bourbon

#81631e
Notes

Calm Bourbon (#81631E) is a deep amber 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 (42°, 62%, 31%) 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.

Etymology

Calm
adjective

Latin calma, heat of the day — paradoxically drifted in Italian to mean stillness. Used as a color modifier since the seventeenth century for hues that read as untroubled. Calm blue, calm gray: moderate saturation combined with optical quiet. Sits at the crisp-bucket near quiet and steady.

Bourbon
noun

American corn-based whiskey — distilled and aged in new charred-oak barrels under U.S. federal regulation. The charring gives bourbon its characteristically saturated warm brown color. The color refers to a 10-year-old Kentucky straight bourbon: a saturated, slightly red-shifted warm brown with the optical depth of new-oak-aged spirit.
