Stripped Wool Verdigris

#40a9a9
Notes

Stripped Wool Verdigris (#40A9A9) is a true cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (180°, 45%, 46%) 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

Stripped
adjective

Old English stripian, to strip — past-participle of strip. As a color modifier, stripped implies a clear-and-bared-and-unornamented quality, the crisp color of Cistercian-and-Bauhaus anti-ornamental stripped-down architectural interior. Sits at the crisp-and-stripped end of the grid, parallel to spare and bare in usage.

Wool
modifier

Old English wull, wool. As a color modifier, wool implies a sheep-fleece-and-warm quality, the visual register of Cotswold-and-Welsh-and-Highland hand-spun-and-hand-woven sheep-fleece-and-felted Cotswold-Welsh-Highland wool-textile surfaces under hand-spun-and-felted-wool textile light. Sits at the modifier-and-texture end of the grid, parallel to silk and yarn 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.
