Profound Alexandria

#310445
Notes

Profound Alexandria (#310445) 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 (282°, 89%, 14%) 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

Profound
adjective

From the Latin profundus, deep — sharing the same root as the noun profundity. As a color modifier, profound is the literary register for deep beyond ordinary measure — used for darks that read as bottomless or inexhaustible. Sits at the dark end of the grid alongside stygian and cavernous, with slightly more dignity and slightly less menace.

Alexandria
noun

Hellenistic Egyptian capital founded by Alexander the Great (332 BCE) — the Library of Alexandria's parchment dye works produced Tyrian purple manuscript-binding leather for the imperial Roman library. Alexandria color refers to a Library of Alexandria-bound Tyrian parchment fragment: a saturated, slightly cool deep violet with the matte finish of multi-bath Murex shellfish dye on tanned Egyptian goatskin.
