Courteous Pewter

#230331
Notes

Courteous Pewter (#230331) is a deep violet 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 (282°, 88%, 10%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Courteous
adjective

Old French cortois, of-the-court — adjectival suffix -ous. As a color modifier, courteous implies a neutral-and-formal-and-polite quality where the hue carries the visual register of Edwardian-and-Belle-Époque formal-and-courteous-of-the-court interior-decoration-and-dress-attire coordinated-color tone. Sits at the neutral-and-friendly end of the grid, parallel to mannerly and polite in usage.

Pewter
noun

An alloy of tin with copper, antimony, and (historically) lead — pre-industrial tableware metal of European households before china replaced it in the eighteenth century. The color refers to a Georgian pewter tankard: a soft, slightly muted gray with the satin finish of a cast and polished alloy. Cooler than bronze, warmer than silver, with the archaic-domestic weight of a metal that aged darker as households used it.

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.
