Shadowed Ravenna
Shadowed Ravenna (#2F2270) is a deep 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 (250°, 53%, 29%) 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
The past participle of shadow, used adjectivally for a color that reads as if partially in shadow rather than fully lit. Implies the slight darkening and cooling that any color undergoes when light is reduced — not the absence of color but the muting of it. Sits in the deep-and-cool end of the engine's grid, lighter than inky and warmer than somber.
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.
