Frank Witchhazel

#839a36
Notes

Frank Witchhazel (#839A36) is a true yellow 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 (74°, 48%, 41%) 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 indigo. 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.

Witchhazel
noun

Hamamelis virginiana, the North American shrub whose distinctive yellow ribbon-petaled flowers bloom in late autumn — and whose bark and leaves yield the astringent witch hazel extract. The color refers to a fresh Hamamelis bloom in November: a saturated, slightly red yellow with the satin finish of crinkled-ribbon petal.
