Flamboyant Atoll

#3fc76d
Notes

Flamboyant Atoll (#3FC76D) is a true green with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (140°, 55%, 51%) 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

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.

Atoll
noun

A ring-shaped coral reef enclosing a central lagoon — the geological signature of subsiding volcanic islands ringed by upward-growing coral. Atoll color refers to the unifying blue-green of a Maldivian-style atoll lagoon seen from above: a saturated, slightly cool deep blue-green with the optical clarity of shallow tropical water.

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.
