Smoldering Jú

#b75e01
Notes

Smoldering Jú (#B75E01) is a true 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 (31°, 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Smoldering
adjective

The progressive participle of smolder, to burn slowly without flame. Used as a color word since the late nineteenth century for the deep reds and oranges of barely-flame coal — the warm saturated darks where the heat is internal rather than emitted. Sits in the bold-and-warm corner, slightly less luminous than burning and slightly less calm than rich.

noun

The Chinese name for the mandarin orange — Citrus reticulata — cultivated in southern China for at least four thousand years. Jú-zǐ (mandarin-fruit) appears in Tang-dynasty poetry as a symbol of autumn abundance and homesickness. The color refers to a Chinese new-year : a saturated, slightly red-shifted orange with the matte finish of cultivated citrus rind. The Chinese cousin of mikan.
