Twinkling Hunter

#42ad1b
Notes

Twinkling Hunter (#42AD1B) 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 (104°, 73%, 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Twinkling
adjective

Old English twinclian, to wink rapidly — present-participle of twinkle. As a color modifier, twinkling implies a saturated-and-rapid-flicker-reflective quality, the bright color of Christmas-fairy-light and night-sky-star atmospheric-scintillation. Sits at the bright-and-reflective end of the grid, parallel to sparkling and glittering in usage.

Hunter
noun

A deep, slightly muted green named for the wool jackets worn by British and American sportsmen for shooting and hunting since the late nineteenth century — chosen for camouflage in temperate woodland. The color refers to the dye on a traditional hunter-green Barbour or tweed: a deep, slightly blue-shifted green with the matte finish of a heavyweight wool. Darker than forest, cooler than holly.

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.
