Buttressed Anthurium

#8b257a
Notes

Buttressed Anthurium (#8B257A) is a true magenta 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 (310°, 58%, 35%) 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

Buttressed
adjective

Old French bouterez, thrusting-mass — past-participle of buttress, derived from bouter (to thrust). As a color modifier, buttressed implies a saturated-and-architecturally-supported quality, the deep-rich color of Gothic-Cathedral flying-buttress-and-rib-vault stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and reinforced.

Anthurium
noun

Central- and South-American flamingo flower (Anthurium andraeanum) — a Araceae tropical perennial cultivated worldwide for its deep-magenta heart-shaped spathe surrounding the spadix. Anthurium color refers to a fully opened Anthurium andraeanum spathe-and-spadix: a saturated, slightly cool deep magenta with the glossy finish of waxy-cuticular spathe surface. The Greek genus name anthos (flower) and ourá (tail) refers to the spadix.
