Punchy Ravenna

#4250b2
Notes

Punchy Ravenna (#4250B2) 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 (233°, 46%, 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Punchy
adjective

A modern adjectival form of punch, to strike sharply. Used as a color word since the early twentieth century for hues that read as highly contrasting and visually loud. Punchy red, punchy yellow: the implication is full saturation combined with optical impact. Sits across the bold and bright buckets, near vivid and striking.

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.
