Frank Stole Verdigris

#53c3bf
Notes

Frank Stole Verdigris (#53C3BF) 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 (178°, 48%, 55%) 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

Frank
adjective

From the Old French franc, free, sincere — used as a color modifier since the seventeenth century for hues that read as direct and unhedged. Frank red, frank brown: moderate-to-high saturation combined with optical directness. Sits at the crisp-bucket alongside direct and honest.

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.
