Spartan Ravenna

#474fac
Notes

Spartan Ravenna (#474FAC) is a true 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°, 42%, 48%) places it in the balanced 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Spartan
adjective

Greek Spartiátēs, of Sparta — adjectival suffix referring to the Lacedaemonian warrior city. As a color modifier, spartan implies a saturated-and-disciplined-and-formal quality, the deep-rich color of Spartan-hoplite military-class crimson-and-bronze armor-and-cloak. Sits at the bold-and-formal end of the grid, parallel to austere and stern in tone.

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.
