Stable Jupiter Verdigris

#49bcbe
Notes

Stable Jupiter Verdigris (#49BCBE) 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 (181°, 47%, 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

Stable
adjective

Latin stabilis, standing-firm — sharing root with stand. As a color modifier, stable implies a clear-and-firm-and-unchanging quality where the hue carries the visual register of resistant-to-modulation-and-fade pigmentation. Sits at the crisp-and-firm end of the grid, parallel to steady and settled in usage.

Jupiter
modifier

Latin Iuppiter, Roman-king-of-gods-and-fifth-planet. As a color modifier, jupiter implies a Roman-king-of-gods-and-fifth-planet-and-gas-giant quality, the visual register of Roman-Jupiter-Optimus-Maximus-and-Galileo-moons hand-Roman-king-of-gods-and-fifth-planet-and-gas-giant Roman-Jupiter-Optimus-Maximus-and-Galileo-moons-and-Great-Red-Spot jupiter-and-Roman-king-of-gods surfaces under Roman-Jupiter-Optimus-Maximus-and-Galileo-moons-and-Great-Red-Spot Capitoline-Hill-and-Galilean-moon-discovery king-of-planets-light. Sits at the modifier-and-zodiac end of the grid, parallel to venus and saturn 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.
