Valiant Kew

#337c21
Notes

Valiant Kew (#337C21) 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 (108°, 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

Valiant
adjective

Latin valēns, strong — present-participle of valēre, sharing root with English value and valor. As a color modifier, valiant implies a saturated-and-courageous-and-firm quality, the deep-rich color of Crusader-and-Knight-Templar military-religious-order vestment. Sits at the bold-and-chivalrous end of the grid, parallel to gallant and heroic in usage.

Kew
noun

The Royal Botanic Gardens at Kew — established 1840 in southwest London, the world's largest collection of botanical research material. Kew color refers to the saturated green of the Palm House interior: a deep, slightly cool deep green with the optical depth of tropical-foliage understory.
