Bold Comfrey

#63861b
Notes

Bold Comfrey (#63861B) is a deep lime 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 (80°, 66%, 32%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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.

Comfrey
noun

Symphytum officinale, the European medicinal plant whose green leaves and root were used in traditional European bone-setting and wound treatment — also known as boneset or knitbone. Comfrey color refers to fresh comfrey leaves on a hedge bank: a soft, slightly muted gray-green with the matte finish of pubescent leaf surface. Cooler than nettle.

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.
