Rugged Anemone

#513fa5
Notes

Rugged Anemone (#513FA5) is a true indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (251°, 45%, 45%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Rugged
adjective

Old Norse rugga, rough / coarse — adjectival suffix -ed. As a color modifier, rugged implies a saturated-and-rough-and-weathered quality, the deep-rich color of Scottish-Highlands-and-Norwegian-fjord outdoor-and-mountain landscape. Sits at the bold-and-weathered end of the grid, parallel to tough and sinewy in usage.

Anemone
noun

The genus Anemone — Greek for windflower, the small spring perennial whose papery petals tremble in the slightest breeze. The color refers to a fresh deep-purple Anemone coronaria in March bloom: a saturated, slightly red-shifted deep purple-blue with the satiny finish of a five-petaled cup. Cooler than amethyst, warmer than indigo, with the Mediterranean-garden weight of a flower painted in Persian miniature and Italian fresco alike.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
