Vitreous Comfrey

#436a0f
Notes

Vitreous Comfrey (#436A0F) 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 (86°, 75%, 24%) 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

Vitreous
adjective

Latin vitreus, glass-like — derived from vitrum (glass). As a color modifier, vitreous implies a clear-and-glassy quality where the hue carries the optical clarity of polished crown-glass. Sits at the crisp-and-clear end of the grid, parallel to pellucid and crystalline in usage.

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.
