Workmanlike Wool Verdigris

#27acab
Notes

Workmanlike Wool Verdigris (#27ACAB) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (180°, 63%, 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

Workmanlike
adjective

Old English weorcmann, workman — adjectival suffix -like. As a color modifier, workmanlike implies a clear-and-skilled-and-honest quality where the hue carries the visual register of journeyman-craftsman careful-and-competent hand-built craft. Sits at the crisp-and-functional end of the grid, parallel to functional and practical 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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

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.
