Flamboyant Tide

#42e8fe
Notes

Flamboyant Tide (#42E8FE) is a true cyan 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 (187°, 99%, 63%) 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.

Tide
noun

The slow flow of seawater driven by lunar gravity — the daily cycle of high to low and back. Tidal and tide used as a color refer to the deep blue-green of coastal water at mid-tide on an overcast day: a soft, slightly muted blue-green with the optical complexity of water in motion. Cooler than reef, deeper than seafoam, with the ecological weight of a force that has shaped every coastline on Earth.

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.
