Resolute Calabasa

#b53a07
Notes

Resolute Calabasa (#B53A07) 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 (18°, 93%, 37%) 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.

Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

The color is a saturated, slightly red orange with the matte finish of cooked vegetable. Warmer than carrot, drier than tangerine. The Spanish cousin of pumpkin.
