Imperial Alexandria

#7b1673
Notes

Imperial Alexandria (#7B1673) 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 (305°, 70%, 28%) 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

Imperial
adjective

From the Latin imperialis, of the empire — applied to color since the medieval period for the hues reserved for sovereigns and empires: imperial purple of Tyrian dye, imperial yellow of Ming-dynasty porcelain. As a modifier, imperial implies saturation combined with the institutional weight of a color owned by a court. Sits in the bold-and-deep corner, alongside royal.

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.
