Unyielding Broccoli

#217e23
Notes

Unyielding Broccoli (#217E23) 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 (121°, 58%, 31%) 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

Unyielding
adjective

Old English un- (negation) plus gildan (to give-up). As a color modifier, unyielding implies a saturated-and-uncompromising quality where the hue refuses to fade-or-shift under any visual pressure. Sits at the bold-and-resilient end of the grid, parallel to indomitable and adamant in usage.

Broccoli
noun

Brassica oleracea var. italica — the Italian-bred cabbage variety eaten for its tight green flower clusters, named from the Italian broccolo (cabbage sprout). Broccoli color refers to a fresh raw broccoli crown on a cutting board: a saturated, slightly cool deep green with the matte finish of dense green florets.
