Frank Sphene

#cf8f34
Notes

Frank Sphene (#CF8F34) is a true amber with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (35°, 62%, 51%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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.

Sphene
noun

A calcium-titanium silicate gem — also called titanite — known for its high dispersion (more than diamond) and its yellow-to-greenish-yellow body color. Mined principally in Madagascar, Brazil, and Pakistan. The color refers to a faceted Madagascar sphene: a saturated, slightly cool yellow-green with the gem's signature internal fire.
