Hollowed Nocturne
Hollowed Nocturne (#332F91) 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 (242°, 51%, 38%) 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
Old English holh, hollow — past-participle of hollow. As a color modifier, hollowed implies the deep-and-cavernous-and-architectural quality of carved-out-cave-and-tunnel interior, particularly the Cappadocian and Lalibela hand-carved rock-cut churches and underground cities. Sits at the deep-and-architectural end of the grid, parallel to cavernous with hand-carved register.
French nocturne, night-piece — adopted into music by John Field (Irish, 1812) and Frédéric Chopin (Polish, 1827–46) for piano character pieces evoking nighttime, and into painting by James McNeill Whistler for a series of deep-blue-violet Thames-river twilights. Nocturne color refers to a Whistler Nocturne in Black and Gold foreground tonality: a saturated, slightly cool deep blue-violet with the soft finish of thinned oil over warm gesso.
