Regional Velvet

#180124
Notes

Regional Velvet (#180124) is a deep indigo 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 (279°, 95%, 7%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Regional
adjective

Latin regiōnālis, of-a-region — adjectival suffix -al. As a color modifier, regional implies a neutral-and-local-and-traditional quality, the neutral color of Provençal-and-Tuscan-and-Catalan regional-and-local-tradition interior-decoration-and-textile traditional-craft surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to provincial and vernacular in usage.

Velvet
noun

A short-pile woven fabric — silk, cotton, or rayon — whose densely packed vertical fibers absorb almost all incident light, producing a deeper black than the dye alone could give. The color refers to a black silk velvet: a deep, slightly muted black with the velvet's signature optical depth and the directional shading that distinguishes it from any flat fabric. Cooler than sable, deeper than ink.
