Hollowed Cleome

#40183c
Notes

Hollowed Cleome (#40183C) is a deep violet 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 (306°, 45%, 17%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Hollowed
adjective

Old English holh, hollow — past-participle of hollow. As a color modifier, hollowed implies the deep-and-cavernous-and-architectural quality of carved-out-cave-and-tunnel interior, particularly the Cappadocian and Lalibela hand-carved rock-cut churches and underground cities. Sits at the deep-and-architectural end of the grid, parallel to cavernous with hand-carved register.

Cleome
noun

Spider flower (Cleome hassleriana) — a tall South American annual cultivated worldwide for its long-stamened pink-and-violet airy racemes. Cleome color refers to a fully bloomed Cleome hassleriana terminal raceme: a saturated, slightly cool deep violet with the velvet finish of fresh four-petaled long-stamened spider-flower corollas. The genus name comes from the Greek kleíō, to enclose, after the bud-cluster structure.
