Buttressed Marigold

#8b2303
Notes

Buttressed Marigold (#8B2303) is a deep red 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 (14°, 96%, 28%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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.

Marigold
noun

Tagetes, the Mexican marigold central to the Día de los Muertos altars where the orange flowers guide the dead home. The English name once referred to the European Calendula officinalis before the Aztec import took the word over. The color is a saturated, almost fluorescent orange-yellow — the carotenoid pigments give marigolds the same chemistry as egg yolks, autumn leaves, and the feathers of flamingos.

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.
