Reliable Gloss Verdigris

#12ab92
Notes

Reliable Gloss Verdigris (#12AB92) is a true teal 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 (170°, 81%, 37%) places it in the highly saturated band at a mid 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Reliable
adjective

Latin re-ligāre, to bind back — adjectival suffix -able. As a color modifier, reliable implies a clear-and-trustworthy-and-consistent quality where the hue carries the visual register of dependable-and-consistent design-element. Sits at the crisp-and-honest end of the grid, parallel to dependable and trustworthy in usage.

Gloss
modifier

Old Norse glosi, glossy-shine. As a color modifier, gloss implies a polished-and-reflective-shine quality, the visual register of polished-and-glossy-leather-and-lacquer hand-polished-and-glossy lacquer-and-shellac-and-varnish polished-and-glossy-shine surfaces under polished-and-glossy-lacquer workshop-light. Sits at the modifier-and-texture end of the grid, parallel to sheen and shine in usage.

Verdigris
noun

The basic copper carbonate that forms on weathered copper and bronze — the pigment scraped from oxidized metal and used in Renaissance painting before being supplanted by more stable greens. The color refers to a thick verdigris on aged copper roofing or the Statue of Liberty's surface: a soft, slightly muted blue-green with the powdery finish of mineral oxide. Cooler than patina, warmer than seafoam, with the archaeological weight of a mineral made by time.
