Resolute Geneva

#587aef
Notes

Resolute Geneva (#587AEF) is a true blue with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (226°, 83%, 64%) 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 amber. 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.

Geneva
noun

Lake Geneva — Lac Léman in French — the largest Alpine lake, between Switzerland and France. Geneva color refers to Lake Geneva water at Montreux in midsummer: a saturated, slightly cool deep blue with the optical depth of Alpine glacier-fed lake.
