Dependable Peplos Verdigris

#57aea3
Notes

Dependable Peplos Verdigris (#57AEA3) is a true teal 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 (172°, 35%, 51%) 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

Dependable
adjective

Latin dē-pendere, to hang from — adjectival suffix -able. As a color modifier, dependable implies a clear-and-trustworthy-and-consistent quality where the hue carries the visual register of consistently-performing-and-counted-on design-element. Sits at the crisp-and-honest end of the grid, parallel to reliable and trustworthy in usage.

Peplos
modifier

Greek πέπλος, Hellenic-women's-robe. As a color modifier, peplos implies a Hellenic-women's-peplos-and-pinned-shoulder quality, the visual register of Hellenic-peplos-and-Athena-Parthenos hand-Hellenic-women's-peplos-and-pinned-shoulder Hellenic-peplos-and-Athena-Parthenos-and-Panathenaic-festival peplos-and-Hellenic-women's-peplos surfaces under Hellenic-peplos-and-Athena-Parthenos-and-Panathenaic-festival Athenian-Acropolis-and-Panathenaic-procession Hellenic-court-light.

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.
