Sunlit Gentian

#12d8e5
Notes

Sunlit Gentian (#12D8E5) is a true cyan 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 (184°, 85%, 48%) 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

Sunlit
adjective

Old English sunne (sun) plus past-participle līehted. As a color modifier, sunlit implies a saturated-and-direct-sunlight-illuminated quality, the bright color of southern-Mediterranean and Greek-island afternoon-sun direct-illumination surface emission. Sits at the bright-and-warm end of the grid, parallel to radiant and brilliant 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.
