Buttressed Pelt Brick

#aa3b20
Notes

Buttressed Pelt Brick (#AA3B20) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (12°, 68%, 40%) 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 cyan. 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.

Pelt
modifier

Old French pellete, small-skin. As a color modifier, pelt implies a fur-with-skin-and-hide quality, the visual register of fur-trapper-and-Hudson-Bay-Pelt hand-trapped-and-skinned beaver-and-otter-and-mink hand-trapped-fur-pelt-and-hide surfaces under Hudson-Bay-and-fur-trapper hand-trapped pelt-and-hide trading-post light. Sits at the modifier-and-texture end of the grid, parallel to hide and fur in usage.

Brick
noun

Fired clay, mineral red. The color refers to common building brick — iron-rich earthenware kilned to the specific dusky red-orange of a Victorian terrace, a Roman aqueduct, an adobe wall in New Mexico. Less saturated than ruby, warmer than burgundy, with a chalky cast that reads as architectural rather than decorative.

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.
