Rugged Suo

#a83383
Notes

Rugged Suo (#A83383) is a true magenta 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 (319°, 53%, 43%) 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 green. 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.

Suo
noun

Japanese 蘇芳, sappan-wood dye (Caesalpinia sappan) — derived from a Southeast Asian tree's heartwood, imported to Japan since the Nara period (710–794) for dyeing court robes a deep red-purple. Suo color refers to a suo-dyed Heian-period silk kinu: a saturated, slightly cool deep magenta with the silk luster of multi-bath sappan-wood dye on tussah silk. Distinct from akane (madder) and beni (safflower).
