Sterile Tufted Verdigris

#3fa79e
Notes

Sterile Tufted Verdigris (#3FA79E) 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 (175°, 45%, 45%) 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

Sterile
adjective

Latin sterilis, barren / not-fertile — sharing root with Greek steiros (barren). As a color modifier, sterile implies a clear-and-medical-clean-and-stripped quality, the crisp color of operating-theater surgical-environment white-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and hygienic in usage.

Tufted
modifier

Old French touffe, tuft. As a color modifier, tufted implies a hand-tufted-and-puffed quality, the visual register of Edwardian-and-Belle-Époque-tufted-upholstery hand-tufted-and-puffed-and-upholstered velvet-and-silk-and-leather tufted-and-puffed-upholstery surfaces under Edwardian-and-Belle-Époque hand-tufted-upholstery-and-cushion light. Sits at the modifier-and-texture end of the grid, parallel to fluff and flock 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.
