Flamboyant Spit Turquoise

#21bde7
Notes

Flamboyant Spit Turquoise (#21BDE7) 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 (193°, 80%, 52%) 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

Flamboyant
adjective

French flamboyant, flaming — present-participle of flamboyer, derived from flambe (flame). As a color modifier, flamboyant implies a saturated-and-attention-grabbing-and-elaborate quality, the bright color of Late-Gothic-and-Rococo highly-decorative-architectural ornament. Sits at the bright-and-flamboyant end of the grid, parallel to showy and ostentatious in usage.

Spit
modifier

Old English spitu, narrow point of land. As a color modifier, spit implies a narrow-projection quality, the visual register of Cape-Cod-and-Spurn-Head narrow-tide-deposited sand-spit-and-shingle hand-walked coastal surfaces extending into open water. Sits at the modifier-and-place end of the grid, parallel to strand and cay 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
