Frank Burlap

#644a14
Notes

Frank Burlap (#644A14) 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 (41°, 67%, 24%) 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

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.

Burlap
noun

A coarse fabric woven from jute or hemp fiber — used historically for sacking, packing, and rough farm-clothing. The color refers to undyed natural burlap: a soft, slightly muted warm tan with the textured matte finish of bast-fiber weave. Drier than hemp, warmer than canvas.
