Buttressed Cotswold

#bf721e
Notes

Buttressed Cotswold (#BF721E) is a true orange with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (31°, 73%, 43%) 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 azure. 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.

Cotswold
noun

The English limestone-built region — and the warm honey-tan of Cotswold limestone used in the cottages and dry-stone walls of Gloucestershire and Oxfordshire. The color refers to a Cotswold cottage facade in afternoon sun: a soft, slightly muted warm tan with the matte finish of weathered porous stone. Drier than honey, warmer than sand.

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.
