Buttressed Kompot

#b03391
Notes

Buttressed Kompot (#B03391) 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 (315°, 55%, 45%) 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.

Kompot
noun

Polish-Russian-Ukrainian kompot — a fruit-based clear-broth drink made from cooked stone-fruit, currants, raspberries, and sour cherries in a deep-magenta liquor. Kompot color refers to a freshly cooled bowl of Polish-Catholic-Lent kompot with floating stone-fruit halves: a saturated, slightly cool deep magenta with the matte finish of anthocyanin-rich mixed-fruit broth in a clear-glass jar.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
