Vaulted Petunia

#321c3c
Notes

Vaulted Petunia (#321C3C) 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 (281°, 36%, 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

Vaulted
adjective

Old French voulte, vault via Latin volūta (rolled) — past-participle of vault. As a color modifier, vaulted implies the deep-and-architectural-and-Gothic quality of Salisbury-Cathedral-and-Chartres-Cathedral nave-vault overhead-stone-arched ceiling. Sits at the deep-and-architectural end of the grid, parallel to cavernous with cathedral-vault register.

Petunia
noun

Petunia × atkinsiana, the modern garden hybrid bred from South American Petunia species in the nineteenth century — now the most-planted annual bedding flower in North America. The color refers to a deep purple petunia in summer container bloom: a saturated, slightly red-shifted deep purple with the satiny finish of trumpet-shaped flowers. Cooler than orchid, warmer than violet, with the bedding-plant weight of a genus bred for nearly endless color and continuous bloom.
