Glowy Polynesia

#21cc81
Notes

Glowy Polynesia (#21CC81) 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 (154°, 72%, 46%) 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

Glowy
adjective

Old English glōwan, to glow — adjectival suffix -y. As a color modifier, glowy implies a saturated-and-soft-emitting-and-warm quality, the bright color of fireside-and-candle-lit interior atmospheric-warmth surface emission. Sits at the bright-and-warm end of the grid, parallel to glowing and luminous in usage.

Polynesia
noun

The vast triangle of Pacific islands — Hawaii, New Zealand, Easter Island, and the islands between. Polynesia refers to the unifying lagoon-blue-green of Polynesian atolls: a saturated, slightly cool deep blue-green with the optical clarity of warm Pacific lagoon water across thousands of cultural-cousin atolls.

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.
