Resolute Spessartine

#a12b05
Notes

Resolute Spessartine (#A12B05) 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 (15°, 94%, 33%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Resolute
adjective

From the Latin resolutus, unwavering — used as a color modifier in literary contexts for hues that read as committed and unmoving. Resolute blue, resolute green: the saturation is full, the hue holds its position without shifting under different light. Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

Spessartine
noun

A manganese-aluminum garnet — orange to red-orange in color, mined principally in Namibia, Mozambique, and California. Spessartine takes its name from the Spessart region of Germany. The color refers to a faceted Namibian spessartine: a saturated, slightly red orange with the gem's signature internal life. Brighter than hessonite.
