Balanced Frieze Verdigris

#33b0b3
Notes

Balanced Frieze Verdigris (#33B0B3) 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°, 56%, 45%) 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

Balanced
adjective

The past participle of balance, to weigh evenly. Used as a color modifier since the eighteenth century for hues that read as neither overcommitted nor restrained. Balanced sage, balanced taupe: moderate saturation combined with optical equilibrium. Sits at the crisp-bucket center alongside even.

Frieze
modifier

Old French frise, band-of-decoration. As a color modifier, frieze implies a horizontal-decorative-band quality, the visual register of Greek-Parthenon-and-Roman-Imperial-frieze hand-carved Doric-and-Ionic-and-Corinthian classical-decorative-frieze architectural surfaces under classical-frieze decorative-band light. Sits at the modifier-and-architecture end of the grid, parallel to eave and plinth 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.
