Vaulted Sidon

#310746
Notes

Vaulted Sidon (#310746) is a deep violet 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 (280°, 82%, 15%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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.

Sidon
noun

Ancient Phoenician city on the Lebanese coast — co-eval with Tyre in Tyrian purple production, and the slightly older of the two purple-dye centers. Sidon color refers to a Sidon-produced Tyrian purple-dyed Phoenician trade textile: a saturated, slightly cool deep violet with the matte finish of multi-bath Hexaplex trunculus shellfish dye on hand-loomed Levantine cloth.
