Dazzling Indicolite

#3fb1fb
Notes

Dazzling Indicolite (#3FB1FB) is a true azure 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 (204°, 96%, 62%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Dazzling
adjective

The progressive participle of dazzle, to overwhelm with brightness — used as a color word since the seventeenth century for hues that read as intense enough to be momentarily blinding. Dazzling white, dazzling pink: the implication is luminance pushed to the extreme. Sits at the bright-bucket extreme alongside electric.

Indicolite
noun

A blue variety of tourmaline — colored by trace iron, mined principally in Brazil, Mozambique, and Pakistan. The color refers to a faceted Brazilian indicolite: a saturated, slightly cool deep blue-green with the gem's signature internal warmth. Cooler than aquamarine.
