Striking Romaine

#acf77f
Notes

Striking Romaine (#ACF77F) is a soft 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 (98°, 88%, 73%) places it in the highly saturated band at a light 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Striking
adjective

The progressive participle of strike, to hit. Used as a color word since the seventeenth century for hues that command immediate attention. Striking red, striking blue: the implication is saturation combined with visual impact. Sits at the bright-bucket center alongside bold and punchy.

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.

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.
