Buttressed Kohbai
Buttressed Kohbai (#87266B) is a deep 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 (317°, 56%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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
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.
Japanese 紅梅, red plum-blossom (Prunus mume var. kohbai) — the deep-pink-flowered cultivar of Japanese plum, a traditional New Year color in Heian-period kasane no irome layered silks. Kohbai color refers to a fully bloomed kohbai plum branch in February: a saturated, slightly cool deep magenta with the velvet finish of fresh plum-blossom petals against bare branches in early-spring snow.
