Buttressed Lilac

#bc5ed9
Notes

Buttressed Lilac (#BC5ED9) is a true violet 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 (286°, 62%, 61%) 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.

Lilac
noun

Syringa vulgaris, the Balkan-native shrub whose pale purple panicles perfume European gardens in May. The Persian nilak, bluish, became the Arabic līlak and then the Spanish lila before reaching English in the seventeenth century. The color refers to a fresh lilac flower cluster: a soft, slightly muted pale purple with the matte finish of densely packed four-petaled florets. Lighter than mauve, cooler than orchid.
