Spirited Citrus

#aca603
Notes

Spirited Citrus (#ACA603) is a deep yellow 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 (58°, 97%, 34%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Spirited
adjective

An adjectival form of spirit — used as a color modifier since the seventeenth century for hues that read as animate and characterful. Spirited orange, spirited green: the implication is saturation combined with personality, a color that feels like it has agency. Sits at the bright-bucket center alongside lively and vibrant.

Citrus
noun

The genus Citrus — and a generic yellow color word for the rind of any Citrus fruit. Citrus refers to the average reflectance of a mixed citrus fruit bowl: a saturated, slightly cool deep yellow with the satin finish of waxed citrus rind.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
