Vibrant Galway

#28e5f8
Notes

Vibrant Galway (#28E5F8) 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 (185°, 94%, 56%) 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

Vibrant
adjective

From the Latin vibrare, to shake — used as a color word since the seventeenth century for hues that read as alive and resonant. Vibrant orange, vibrant green: the implication is saturation combined with the optical impression of slight motion or energy. Sits at the bright-bucket center alongside vivid and lively.

Galway
noun

The western Irish county — and the deep blue of Galway Bay and the saturated blue of the Aran Islands-and-Cliffs of Moher coastline. Galway color refers to Galway Bay at midday: a saturated, slightly cool deep blue with the optical depth of cold Atlantic-Irish coastal water.
