Open Mojave

#913b15
Notes

Open Mojave (#913B15) 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 (18°, 75%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Open
adjective

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

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.
