Jazzed Normandy

#31ba42
Notes

Jazzed Normandy (#31BA42) 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 (127°, 58%, 46%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Jazzed
adjective

American slang jazz, liveliness — past-participle of jazz. As a color modifier, jazzed implies a saturated-and-excited-and-active quality, the bright color of American-Jazz-Age poster-and-album-cover saturated-and-rhythmic graphic-design. Sits at the bright-and-active end of the grid, parallel to caffeinated and wired in usage.

Normandy
noun

The French northwestern region — and the saturated green of Pays d'Auge apple-orchard country and the rolling green hills of the bocage Normand. Normandy refers to a Norman countryside in late spring: a saturated, slightly cool deep yellow-green with the matte finish of well-watered dairy pasture.

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.
