Bracing Meteor Turquoise

#18e4d5
Notes

Bracing Meteor Turquoise (#18E4D5) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (176°, 81%, 49%) 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

Bracing
adjective

Old French bracier, to embrace — present-participle of brace. As a color modifier, bracing implies a saturated-and-cool-and-energizing quality, the bright color of Atlantic-Cornish-coast and Hebridean-island fresh-sea-air visual-stimulation. Sits at the bright-and-cool end of the grid, parallel to invigorating and crisp in usage.

Meteor
modifier

Greek μετέωρος, suspended-in-air. As a color modifier, meteor implies a streaking-and-burning-and-shooting-star quality, the visual register of Perseids-and-Leonids-meteor hand-streaking-and-burning-and-shooting-star Perseids-and-Leonids-and-Geminids-meteor meteor-and-streaking-and-burning-and-shooting-star surfaces under Perseids-and-Leonids-and-Geminids-meteor August-and-November-and-December-night-sky shooting-star-light. Sits at the modifier-and-cosmic end of the grid, parallel to comet and nova in usage.

Turquoise
noun

The hydrated copper-aluminum phosphate mined in Persia and the American Southwest for thousands of years — the firuze of Iran, the chalchihuitl of Mesoamerica, the heart of Pueblo and Navajo silverwork. The color refers to a fine Sleeping Beauty turquoise from Arizona: a saturated, slightly green-shifted blue with the slight matrix of host-rock veining. Brighter than persian, lighter than cerulean.
