Buttressed Lohita

#a30d2f
Notes

Buttressed Lohita (#A30D2F) is a true 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 (346°, 85%, 35%) places it in the highly saturated band at a mid 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 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.

Lohita
noun

The Sanskrit word for copper-red — used in Vedic texts and Sanskrit poetry for the slightly metallic red-brown of copper, dried blood, and certain river clays. The color refers to a freshly cleaved copper ore: a soft, slightly muted deep red-brown with the matte finish of copper-and-iron oxide. Drier than copper, warmer than rust.

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.
