Crepuscular Yuzu
Crepuscular Yuzu (#75250B) is a deep orange with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (15°, 83%, 25%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin crepusculāris, of twilight — derived from crepusculum (twilight). As a color modifier, crepuscular implies the deep blue-violet darkness of civil-twilight period between sunset and nightfall. Sits at the deep-and-cool end of the grid, where the hue carries the Belt of Venus atmospheric-scattering quality of clear-sky horizon at dusk.
Citrus junos, the Japanese citrus prized for its aromatic peel — used in yuzu kosho paste, yuzu ponzu, and the yuzu-yu baths of Japanese New Year. The color refers to a fully ripe yuzu in late autumn: a soft, slightly cool yellow-orange with the matte finish of pebbled citrus rind. Cooler than mikan, lighter than tangerine.
