Notes

Easy Cōng (#2C5A18) is a deep 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 (102°, 58%, 22%) 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.

Etymology

Easy
adjective

Old French aisié, comfortable, at rest — used as a color modifier since the eighteenth century for hues that read as visually undemanding. Easy beige, easy gray: moderate saturation combined with optical restfulness. Sits at the crisp-bucket center alongside calm and settled.

Cōng
noun

The Chinese word for scallion — and the bright yellow-green of fresh-cut scallion stalks. Cōnglǜ refers to the saturated lime-green of Chinese cooking and traditional textile color. The color refers to a fresh-sliced scallion: a saturated, slightly yellow-shifted green with the satin finish of cut allium tissue.
