Truthful Honed Verdigris

#4cb6b2
Notes

Truthful Honed Verdigris (#4CB6B2) 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°, 42%, 51%) 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

Truthful
adjective

Old English trēowth, truth — adjectival suffix -ful. As a color modifier, truthful implies a clear-and-honest-and-direct quality where the hue carries the visual register of accurate-and-faithful-representation declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and honest in usage.

Honed
modifier

Old English hǣnan, to-sharpen. As a color modifier, honed implies a sharp-edged-and-polished quality, the visual register of Sheffield-and-Solingen-honed-blade hand-honed-and-sharpened-and-polished steel-and-iron-and-bronze Sheffield-and-Solingen-honed-blade surfaces under Sheffield-and-Solingen hand-honed-and-sharpened-blade workshop-light. Sits at the modifier-and-texture end of the grid, parallel to buffed and gloss 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.
