Caliginous Mojave

#512309
Notes

Caliginous Mojave (#512309) is a deep orange 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 (22°, 80%, 18%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Caliginous
adjective

Latin cālīginōsus, misty / dark — derived from cālīgō (mist, gloom). As a color modifier, caliginous implies an obscured, dimmed, slightly-cool-shifted quality where the hue is veiled by darkness or atmospheric fog. Sits at the deep-and-veiled end of the grid, between murky and tenebrous in usage.

Mojave
noun

The Mojave Desert in southwestern North America — Joshua trees, salt flats, the deep orange-red of weathered Cadillac Range sandstone. Mojave as a color refers to a Mojave sunset over the Amargosa Range: a saturated, slightly red-shifted deep orange with the optical clarity of high-altitude desert air. Drier than tangerine, warmer than pumpkin.
