Plotted Ceres Verdigris

#42ada8
Notes

Plotted Ceres Verdigris (#42ADA8) is a true cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (177°, 45%, 47%) 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

Plotted
adjective

Old English plot, small piece of ground — past-participle of plot. As a color modifier, plotted implies a clear-and-coordinate-mapped quality, the crisp color of Cartesian-and-graph-paper coordinate-plotted scientific-and-engineering data-visualization plot-line. Sits at the crisp-and-mapped end of the grid, parallel to mapped and surveyed in usage.

Ceres
modifier

Latin Ceres, Roman-goddess-of-grain. As a color modifier, ceres implies a dwarf-planet-and-asteroid-belt-and-grain-goddess quality, the visual register of Ceres-dwarf-planet-and-asteroid-belt hand-dwarf-planet-and-asteroid-belt-and-grain-goddess Ceres-dwarf-planet-and-asteroid-belt-and-Dawn-mission ceres-and-dwarf-planet-and-asteroid-belt surfaces under Ceres-dwarf-planet-and-asteroid-belt-and-Dawn-mission inner-asteroid-belt-and-Occator-crater dwarf-planet-light. Sits at the modifier-and-cosmic end of the grid, parallel to vesta and pallas 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.
