Coruscating Mediterranean

#17acfb
Notes

Coruscating Mediterranean (#17ACFB) 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 (201°, 97%, 54%) 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

Coruscating
adjective

Latin coruscāns, flashing — present-participle of coruscāre. As a color modifier, coruscating implies a saturated-and-rapidly-flashing quality, the bright color of lightning-strike atmospheric-electrical-discharge against the night-sky. Sits at the bright-and-flashing end of the grid, parallel to flashing and flickering in usage.

Mediterranean
noun

The sea between Europe, Asia, and North Africa — the cradle of three continents' civilizations and the body of water named, in Latin, the middle of the earth. The color refers to mid-depth Mediterranean water on a clear summer day: a saturated, slightly green-shifted blue with the optical depth of a sea less colored by river silt than the Atlantic. Deeper than aqua, warmer than azure.
