Bold Mullein

#81972c
Notes

Bold Mullein (#81972C) 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 (72°, 55%, 38%) 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

Bold
adjective

Old English beald, brave, courageous — a quality word that crossed over to color in the late seventeenth century. Bold describes a color that asserts itself: high saturation combined with mid lightness, where the hue presents itself without compromise. Sits at the center of the bold-bucket grid, near strong and rich. Closer to a presence word than a pigment word.

Mullein
noun

Verbascum thapsus, the European biennial whose tall yellow flower spikes appear in second-year growth. Used in classical antiquity as a torch (oiled flower spikes) and as a medicinal cough treatment. The color refers to a fresh Mullein flower spike at midsummer: a saturated, slightly cool yellow with the matte finish of small five-petaled flowers along a tall stem.

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.
