Starched Pall Verdigris

#28a9aa
Notes

Starched Pall Verdigris (#28A9AA) 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 (180°, 62%, 41%) 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

Starched
adjective

Old English stercan, to stiffen — past-participle of starch. As a color modifier, starched implies a clear-and-stiff-and-formal quality, the crisp color of Edwardian-period formal-evening-shirt-and-collar starched-and-pressed dress-attire. Sits at the crisp-and-finished end of the grid, parallel to pressed and ironed in usage.

Pall
modifier

Latin pallium, cloak-or-funeral-cover. As a color modifier, pall implies a cloaked-and-shrouded-and-funereal quality, the visual register of Roman-Catholic-and-Anglican-pall hand-cloaked-and-shrouded-and-funereal Roman-Catholic-and-Anglican-and-Orthodox-funeral funeral-pall-and-coffin-shroud-and-altar-cloth surfaces under Roman-Catholic-and-Anglican funeral-pall-and-coffin-shroud cathedral-incense light. Sits at the modifier-and-mood end of the grid, parallel to gloom and shade 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.
