Frank Umbria

#713f0f
Notes

Frank Umbria (#713F0F) 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 (29°, 77%, 25%) 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.

Umbria
noun

The Italian region — and the terra di Siena and terra d'ombra (umber) earth pigments mined there since the Renaissance. Umbria refers to a freshly ground raw umber pigment in oil: a soft, slightly muted warm dark brown with the matte finish of iron-and-manganese earth. Cooler than sienna, deeper than tabacco.
