Quieting Alexandria

#63516d
Notes

Quieting Alexandria (#63516D) is a true indigo 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 (279°, 15%, 37%) places it in the muted band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Quieting
adjective

Latin quiētus, quiet — present-participle of quiet. As a color modifier, quieting implies a hushed-and-soothing-and-calming quality where the hue carries the visual register of gradually-calming-and-quieting ambient-environment color-treatment. Sits at the hushed-and-soft end of the grid, parallel to softening and muting in usage.

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.
