Live Hydrangea

#2fe5fa
Notes

Live Hydrangea (#2FE5FA) 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 (186°, 95%, 58%) 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

Live
adjective

Old English libban, to live — used as a color word since the nineteenth century for hues that read as active or animate. Live wire, live color: the implication is luminance combined with the optical impression of internal motion. Sits in the bright-bucket center alongside vivid and vibrant.

Hydrangea
noun

The genus Hydrangea — particularly H. macrophylla, whose flower color depends on soil pH (acidic = blue, alkaline = pink). The color refers to a blue-bloom H. macrophylla in acidic-soil garden: a saturated, slightly cool deep blue-violet with the matte finish of clustered four-petaled florets.
