Flamboyant Lazuli

#4deffc
Notes

Flamboyant Lazuli (#4DEFFC) 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 (184°, 97%, 65%) 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.

Lazuli
noun

Passerina amoena, the lazuli bunting — a North American songbird whose males display saturated deep-blue plumage with white wing bars and chestnut breasts. Named for the gemstone (lapis lazuli) the bird's plumage resembles. The color refers to a male lazuli bunting in breeding plumage: a saturated, slightly cool deep blue.
