Mapped Saint Verdigris

#1cb2b4
Notes

Mapped Saint Verdigris (#1CB2B4) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (181°, 73%, 41%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Mapped
adjective

Latin mappa, cloth / napkin — past-participle of map. As a color modifier, mapped implies a clear-and-cartographic-and-surveyed quality, the crisp color of Ordnance-Survey-and-USGS scientific-and-cadastral cartographic-and-topographic mapping-and-projection. Sits at the crisp-and-mapped end of the grid, parallel to plotted and surveyed in usage.

Saint
modifier

Latin sanctus, holy. As a color modifier, saint implies a hagiographic-and-relic quality, the visual register of Greek-Orthodox-and-Roman-Catholic-Saint hand-painted icon-and-relic-and-halo-and-iconostasis hagiographic surfaces under Greek-Orthodox-and-Roman-Catholic hand-painted icon-and-iconostasis hagiographic-tradition candlelight. Sits at the modifier-and-cultural end of the grid, parallel to monk and friar 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.

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.
