Fortified Lohita

#b41303
Notes

Fortified Lohita (#B41303) 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 (5°, 97%, 36%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fortified
adjective

Latin fortificāre, to make strong — past-participle of fortify. As a color modifier, fortified implies a saturated-and-strengthened-and-defensive quality, the deep-rich color of Vauban-style military-fortification stone-and-earth rampart-and-bastion architecture. Sits at the bold-and-fortified end of the grid, parallel to bastioned and armored.

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.
