Frank Bourbon

#54491c
Notes

Frank Bourbon (#54491C) is a deep amber with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (48°, 50%, 22%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Frank
adjective

From the Old French franc, free, sincere — used as a color modifier since the seventeenth century for hues that read as direct and unhedged. Frank red, frank brown: moderate-to-high saturation combined with optical directness. Sits at the crisp-bucket alongside direct and honest.

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.
