Fresh Glide Verdigris

#37a6a3
Notes

Fresh Glide Verdigris (#37A6A3) 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 (178°, 50%, 43%) 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

Fresh
adjective

Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new in usage.

Glide
modifier

Old English glīdan, to-move-smoothly. As a color modifier, glide implies a smooth-and-silent-and-frictionless quality, the visual register of swan-and-skater-glide hand-smooth-and-silent-and-frictionless swan-and-skater-and-soaring-albatross glided-and-smooth-and-silent-and-frictionless surfaces under swan-and-skater-and-soaring-albatross frozen-pond-and-Hyde-Park-Serpentine-and-open-ocean smooth-flight-light. Sits at the modifier-and-mood end of the grid, parallel to float and hover 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.
