Ignited Hydrangea

#31f0fc
Notes

Ignited Hydrangea (#31F0FC) 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°, 97%, 59%) 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

Ignited
adjective

Latin ignīre, to set on fire — past-participle of ignite. As a color modifier, ignited implies a saturated-and-just-started-burning quality, the bright color of match-strike-and-flint-spark initial-combustion emission. Sits at the bright-and-warm end of the grid, parallel to kindled and aflame in usage.

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.
