Booming Loden

#257a21
Notes

Booming Loden (#257A21) 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 (117°, 57%, 30%) 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

Booming
adjective

Imitative-onomatopoeic origin — present-participle of boom, sharing root with Dutch bommen. As a color modifier, booming implies a saturated-and-loud-and-confident quality where the hue announces itself with full visual amplitude. Sits at the bold-and-resonant end of the grid, parallel to resounding and thunderous.

Loden
noun

The traditional Austrian wool fabric — densely woven, water-resistant, and used in the heavy hunting coats and Tyrolean walking jackets of Alpine winter dress. Loden color refers to the dark forest-green of traditional loden cloth: a deep, slightly muted dark green with the matte finish of fulled wool. The Tyrolean cousin of hunter.
