Flat Mangrove

#2a8b74
Notes

Flat Mangrove (#2A8B74) is a true teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (166°, 54%, 35%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Flat
adjective

Old Norse flatr, flat / level. As a color modifier, flat implies a clear-and-evenly-spread quality where the hue carries the matte-finish visual register of unmodulated single-plane surface. Sits at the crisp-and-balanced end of the grid, parallel to level and even in usage.

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.
