Brilliant Mangrove

#28f3c0
Notes

Brilliant Mangrove (#28F3C0) is a true teal 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 (165°, 89%, 55%) 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

Brilliant
adjective

From the Italian brillante, sparkling — used as a color modifier since the seventeenth century for hues that read as optically active beyond their literal saturation. Brilliant green, brilliant blue: the implication is luminance combined with the slight sparkle of a high-refractive surface. Sits at the bright-bucket center alongside vivid and bright.

Mangrove
noun

Tropical-coastal salt-tolerant trees — Rhizophora, Avicennia, Bruguiera — whose tangled prop-roots define tropical estuaries from Florida to Borneo. Mangrove color refers to mature mangrove foliage seen against tidal water: a saturated, slightly cool deep blue-green with the matte finish of dense salt-adapted leaves.

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.
