Rugged Porpora

#a82324
Notes

Rugged Porpora (#A82324) 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 (360°, 66%, 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.

Porpora
noun

The Italian word for the imperial purple of Roman tradition — derived from murex shells but borrowed in modern Italian color vocabulary for a deep, slightly red-shifted purple-red. The color refers to porpora-dyed Venetian silk: a saturated, slightly cool deep red-purple with the satin finish of plant-and-shell dye. Cooler than crimson, warmer than burgundy.

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.
