Resilient Nori

#27640a
Notes

Resilient Nori (#27640A) is a deep green 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 (101°, 82%, 22%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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.

Etymology

Resilient
adjective

Latin resiliēns, springing-back — present-participle of resilīre. As a color modifier, resilient implies a saturated-and-recovering-and-flexible quality where the hue maintains its strength under visual pressure. Sits at the bold-and-resilient end of the grid, parallel to tough and hardy 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.
