Resolute Forsythia
Resolute Forsythia (#809913) 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 (71°, 78%, 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
Forsythia × intermedia, the East Asian shrub naturalized in European gardens — and the bright yellow flowers that cover bare branches in early spring before the leaves emerge. The color refers to a fresh Forsythia bloom in March: a saturated, slightly red-shifted bright yellow with the matte finish of small four-petaled flowers covering an entire shrub.
