Vaulted Banafsheh

#311d8b
Notes

Vaulted Banafsheh (#311D8B) is a deep indigo 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 (251°, 65%, 33%) 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 yellow. 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.

Banafsheh
noun

Persian بنفشه, the Viola odorata sweet violet — the diminutive of banafsh, used for the flower itself rather than the color. Banafsheh is a stock floral motif in Iranian poetry (Hafez, Rumi) symbolizing transient beauty. Banafsheh color refers to a freshly opened Viola odorata petal: a saturated, slightly cool deep blue-violet with the velvet finish of a fresh viola petal.
