Buttressed Pompeii

#871349
Notes

Buttressed Pompeii (#871349) is a deep magenta with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (332°, 75%, 30%) 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 teal. 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.

Pompeii
noun

The Roman city buried by Vesuvius's 79 CE eruption — and the deep saturated red used on the wall frescoes preserved by the ash, named Pompeian Red for the place. The color refers to the Villa of the Mysteries fresco background: a saturated, slightly cool deep red with the matte finish of cinnabar-and-iron-oxide pigment in lime plaster. Deeper than crimson, cooler than vermillion.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
