Dazzling Brook

#18cb87
Notes

Dazzling Brook (#18CB87) is a true teal with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (157°, 79%, 45%) 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 magenta. 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.

Brook
noun

A small natural stream — smaller than a creek, particularly the spring-fed brooks of New England and northern Britain. Brook color refers to a clear-bottomed mountain brook seen against pebble bed: a soft, slightly cool pale blue-green with the optical clarity of cold spring-fed water.
