Lined Celadon
Lined Celadon (#1D9781) is a true teal with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (169°, 68%, 35%) 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
Old English līne, line / cord — past-participle of line. As a color modifier, lined implies a clear-and-coordinated-and-supported quality where the hue carries the visual register of carefully-lined-and-supported textile-or-print surface. Sits at the crisp-and-finished end of the grid, parallel to trim and coordinated in usage.
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.
