Easy Atlas Verdigris

#28aba8
Notes

Easy Atlas Verdigris (#28ABA8) 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 (179°, 62%, 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

Easy
adjective

Old French aisié, comfortable, at rest — used as a color modifier since the eighteenth century for hues that read as visually undemanding. Easy beige, easy gray: moderate saturation combined with optical restfulness. Sits at the crisp-bucket center alongside calm and settled.

Atlas
modifier

Greek Ἄτλας, Titan-bearing-the-heavens. As a color modifier, atlas implies a Titan-bearing-heaven-and-globe-bearer quality, the visual register of Farnese-Atlas-and-Titanomachy-Atlas hand-Titan-bearing-heaven-and-globe-bearer Farnese-Atlas-and-Titanomachy-Atlas-and-Hellenistic-marble atlas-and-Titan-bearing-heaven surfaces under Farnese-Atlas-and-Titanomachy-Atlas-and-Hellenistic-marble Naples-museum-and-celestial-globe globe-bearer-light. Sits at the modifier-and-myth end of the grid, parallel to titan and zeus 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.
