Established Nori

#288131
Notes

Established Nori (#288131) is a deep green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (126°, 53%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Latin stabilīre, to make stable — past-participle of establish. As a color modifier, established implies a saturated-and-rooted quality where the hue carries the weight of long-standing visual presence. Sits at the bold-and-firm end of the grid, parallel to steadfast and anchored in usage.

Nori
noun

The Japanese name for Pyropia and Porphyra edible seaweeds — pressed into the dried sheets used for makizushi sushi rolls and onigiri rice balls. Nori color refers to a fresh sheet of toasted nori: a deep, slightly cool dark green with the slight optical translucency of pressed marine alga.
