Crisp Agora Celadon

#40c466
Notes

Crisp Agora Celadon (#40C466) is a true green 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 (137°, 53%, 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Crisp
adjective

Latin crispus, curled — drifted in English from the curled hair sense to fresh and clean. As a color modifier, crisp implies saturation combined with optical clarity, with no haze or film between the eye and the surface. Used across the bright and crisp buckets where the hue is fresh-looking. Slightly less assertive than vivid.

Agora
modifier

Greek agora, Greek-marketplace. As a color modifier, agora implies a Greek-and-Athens-marketplace quality, the visual register of Athenian-and-Spartan-Agora hand-built marketplace-and-civic-meeting-square agora-and-stoa-and-bouleuterion classical-Greek architectural surfaces under Athenian-Agora-and-Spartan-Lacedaemon classical light. Sits at the modifier-and-architecture end of the grid, parallel to forum and stoa in usage.

Celadon
noun

The pale-green iron-ash glaze fired on Chinese and Korean stoneware since the Han dynasty — Goryeo celadon and Longquan ware reaching their peak between the tenth and thirteenth centuries. The color refers to a glazed Goryeo bowl in display lighting: a soft, slightly muted green-blue with the high shine of vitrified silica. Cooler than jade, warmer than seafoam, with the museum weight of a ceramic tradition prized in East Asian imperial courts.
