Firm Lohita

#b51701
Notes

Firm Lohita (#B51701) 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 (7°, 99%, 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

Firm
adjective

Latin firmus, strong / stable — sharing root with English farm (originally a fixed-yearly-rental). As a color modifier, firm implies a saturated-and-resolute quality where the hue holds its visual position without wavering. Sits at the bold-and-firm end of the grid, parallel to steadfast and unwavering in usage.

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.
