Fresh Gentian

#2ad3e3
Notes

Fresh Gentian (#2AD3E3) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (185°, 77%, 53%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fresh
adjective

Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new in usage.

Gentian
noun

The genus Gentiana — Alpine and high-meadow perennials whose deep saturated blue flowers are among the bluest in the European flora. Gentian-blue names a color category. The color refers to a fresh G. acaulis (stemless gentian) in Alpine meadow: a saturated, slightly cool deep blue with the matte finish of trumpet-shaped flower.

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.
