Rugged Nasturtium

#b1391b
Notes

Rugged Nasturtium (#B1391B) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (12°, 74%, 40%) 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 cyan. 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.

Nasturtium
noun

Tropaeolum majus, the South American climbing plant naturalized as a kitchen-garden flower across Europe. Nasturtium (from the Latin naris-torquere, nose-twisting, for the peppery flavor) has edible leaves and saturated red-orange flowers. The color refers to a fresh T. majus bloom: a saturated, slightly red orange with the satin finish of bee-pollinated flower. Brighter than carrot.

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.
