Flamboyant Romaine

#78bd31
Notes

Flamboyant Romaine (#78BD31) is a true lime 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 (90°, 59%, 47%) 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 indigo. 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.

Romaine
noun

Lactuca sativa var. longifolia, the upright lettuce variety whose tall green-and-white heads are essential to Caesar salad. Named for Rome, where the Romans cultivated it for European salad tradition. The color refers to a fresh romaine leaf: a soft, slightly cool yellow-green with the satin finish of dewy lettuce.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
