Serviceable Riviera

#a1590e
Notes

Serviceable Riviera (#A1590E) 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 (31°, 84%, 34%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Serviceable
adjective

Latin servītium, service — adjectival suffix -able. As a color modifier, serviceable implies a clear-and-fit-for-purpose-and-durable quality where the hue carries the visual register of long-lasting-and-functional everyday-use design. Sits at the crisp-and-functional end of the grid, parallel to practical and utilitarian in usage.

Riviera
noun

The Mediterranean coast — particularly the Italian Riviera between Genoa and the French border, where stucco facades are limewashed in the warm orange-tan of terra di Genova. Riviera as a color refers to the limewashed walls of a Camogli or Cinque Terre village: a soft, slightly muted warm orange-tan with the matte finish of weathered limewash.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
