Striking Persian

#66cd84
Notes

Striking Persian (#66CD84) 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 (137°, 51%, 60%) 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

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.

Persian
noun

The blue-green of glazed Persian tile and ceramic — the firuze (turquoise) palette that frames Iranian architecture from Isfahan's Shah Mosque to the courtyard fountains of Yazd. The color refers to a polished Persian-tile color sample: a saturated, slightly muted blue-green with the high shine of fired glaze. Cooler than turquoise, warmer than cerulean, with the Islamic-architectural weight of a thousand-year tile tradition.
