Stately Persian

#21a843
Notes

Stately Persian (#21A843) 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 (135°, 67%, 39%) 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

Stately
adjective

An adjectival form of state, condition of dignity. Used as a color modifier since the seventeenth century for the deep saturated jewel tones of formal ceremony — the deep blue of a robes-of-state, the deep red of a state-banquet velvet. Sits in the bold-and-formal corner alongside imperial and royal, with slightly less institutional weight.

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.

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.
