Searing Brook

#28c789
Notes

Searing Brook (#28C789) 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°, 67%, 47%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Searing
adjective

Old English sēarian, to wither — present-participle of sear. As a color modifier, searing implies a saturated-and-burning-touch-hot quality, the bright color of cast-iron-griddle high-heat surface-emission. Sits at the bright-and-warm end of the grid, parallel to scorching and blazing in usage.

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.
