Deathly Beech

#255314
Notes

Deathly Beech (#255314) is a deep green 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 (104°, 61%, 20%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Deathly
adjective

Old English dēath, death — adjectival suffix -ly. As a color modifier, deathly implies a deep-cool-and-pallid quality, the cold-shifted darkness associated with mortality and absence of vital warmth. Sits at the deep-and-cool end of the grid, parallel to funereal but with pallor undertone.

Beech
noun

The genus Fagus — particularly F. sylvatica, the European beech — a deciduous tree whose smooth gray bark and golden-green spring foliage define European temperate woodland. The color refers to fresh beech foliage in May: a saturated, slightly yellow yellow-green with the satin finish of new leaf surface.
