Level Stole Verdigris

#4fb9b9
Notes

Level Stole Verdigris (#4FB9B9) 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°, 43%, 52%) 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

Level
adjective

Latin libella, small-balance / level-tool — sharing root with libra (balance). As a color modifier, level implies a clear-and-horizontal-true quality where the hue carries the visual register of gravity-perpendicular-and-perfectly-horizontal surface. Sits at the crisp-and-balanced end of the grid, parallel to plumb and flat in usage.

Stole
modifier

Latin stola, Roman-women's-and-priestly-robe. As a color modifier, stole implies a Roman-women's-and-priestly-robe quality, the visual register of Roman-stola-and-Catholic-priestly-stole hand-Roman-women's-and-priestly-robe Roman-stola-and-Catholic-priestly-stole-and-Anglican-tippet stole-and-Roman-women's-and-priestly-robe surfaces under Roman-stola-and-Catholic-priestly-stole-and-Anglican-tippet Republican-Rome-and-Catholic-Mass-and-Anglican-Vespers Roman-and-Mass-light. Sits at the modifier-and-textile end of the grid, parallel to cope and robe 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.
