Resolute Wisteria

#66198b
Notes

Resolute Wisteria (#66198B) is a deep violet 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 (281°, 70%, 32%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary green. 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.

Wisteria
noun

The genus Wisteria, the climbing legume vines of East Asia — W. sinensis (Chinese) and W. floribunda (Japanese) — whose pendulous racemes of pale blue-violet flowers drape ten meters of pergola in late spring. The color refers to a fresh wisteria flower cluster: a soft, slightly violet-shifted pale blue with the matte finish of pea-family florets. Lighter than lilac, cooler than periwinkle, with the architectural weight of a vine that ages into structure.

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.
