Frank Beeswing

#905b03
Notes

Frank Beeswing (#905B03) 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 (37°, 96%, 29%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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.

Beeswing
noun

The thin, glassy crust that forms on the inside of a long-aged port or sherry bottle — fragments break loose like the wings of bees as the wine ages. The color refers to a beeswing-rich vintage port: a deep, slightly muted warm gold-brown with the optical complexity of long-cellar-aged fortified wine.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
