Vitreous Rain Verdigris

#2fbbba
Notes

Vitreous Rain Verdigris (#2FBBBA) 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°, 60%, 46%) 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

Vitreous
adjective

Latin vitreus, glass-like — derived from vitrum (glass). As a color modifier, vitreous implies a clear-and-glassy quality where the hue carries the optical clarity of polished crown-glass. Sits at the crisp-and-clear end of the grid, parallel to pellucid and crystalline in usage.

Rain
modifier

Old English regn, rain-or-shower. As a color modifier, rain implies a rain-shower-and-wet-and-Atlantic-front quality, the visual register of Atlantic-front-rain-and-monsoon-rain hand-rain-shower-and-wet-and-Atlantic-front Atlantic-front-rain-and-monsoon-rain-and-Lake-District-deluge rain-and-rain-shower-and-wet surfaces under Atlantic-front-rain-and-monsoon-rain-and-Lake-District-deluge Cumbrian-fells-and-Borrowdale-and-Snowdonia Atlantic-rain-light. Sits at the modifier-and-weather end of the grid, parallel to sleet and flurry 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.
