Plush Ravenna

#171b43
Notes

Plush Ravenna (#171B43) is a deep blue 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 (235°, 49%, 18%) 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

Plush
adjective

From the French peluche, long-haired fabric — borrowed into English in the seventeenth century for the deep-pile velvet imitation that became Victorian upholstery. As a color modifier, plush implies the optical depth that comes from a thick pile absorbing light: plush burgundy, plush emerald. Sits in the dark-and-saturated quadrant near velvet and deep.

Ravenna
noun

Italian late-Roman / early-Byzantine capital (5th–8th centuries) — home of the San Vitale and Sant'Apollinare in Classe basilicas with their iconic deep-blue glass-tessera mosaic vaults. Ravenna color refers to the deep-blue glass-tessera background of San Vitale's Justinian and Theodora mosaic: a saturated, slightly cool deep blue-violet with the glossy finish of Byzantine cobalt-glass tessera under raking light.
