Buttressed Goji

#b52d99
Notes

Buttressed Goji (#B52D99) 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 (312°, 60%, 44%) 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.

Goji
noun

Chinese Lycium barbarum (枸杞) — a Solanaceae shrub native to the Ningxia region of north-central China, whose deep-magenta drupes have been used in Traditional Chinese Medicine for two millennia. Goji color refers to a freshly dried Lycium barbarum drupe-cluster on a Ningxia sun-drying mat: a saturated, slightly cool deep magenta with the matte finish of carotenoid-and-anthocyanin-rich dried-fruit skin.
