Utilitarian Verona

#9c4617
Notes

Utilitarian Verona (#9C4617) is a true 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 (21°, 74%, 35%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Utilitarian
adjective

Latin ūtilitās, usefulness — adjectival suffix -ian. As a color modifier, utilitarian implies a clear-and-purpose-fit-and-stripped-down quality, the crisp color of Shaker-and-Quaker anti-ornamental functional-and-no-frills craft tradition. Sits at the crisp-and-functional end of the grid, parallel to functional and workmanlike in usage.

Verona
noun

The Italian city — and the warm pink-orange of Verona red marble used in the city's medieval Loggia del Consiglio and in San Zeno Maggiore. Verona as a color refers to a polished Verona marble slab: a soft, slightly muted warm pink-orange with the slight veining of mineral inclusions. Cooler than terracotta, warmer than ochre.
