Resolute Yale

#1763f0
Notes

Resolute Yale (#1763F0) is a true azure with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (219°, 88%, 52%) 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.

Yale
noun

The official athletic blue of Yale University — a deep, slightly muted blue chosen in the 1890s and now associated with the university's three-century brand. The color refers to a Yale athletic-jersey blue: a saturated, slightly muted deep blue with the matte finish of dyed wool. Cooler than royal, warmer than navy, with the Ivy-League heraldic weight of a brand color that hasn't shifted in over a century.
