Pure Anemone

#6339d9
Notes

Pure Anemone (#6339D9) is a true indigo with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (256°, 68%, 54%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pure
adjective

Latin purus, clean, unmixed — applied to color since antiquity for hues that contain only one pigment without dilution by white, black, or another color. Pure red is the textbook ideal: high saturation, mid lightness, no shift. Sits at the bold-bucket center, parallel to true and strong.

Anemone
noun

The genus Anemone — Greek for windflower, the small spring perennial whose papery petals tremble in the slightest breeze. The color refers to a fresh deep-purple Anemone coronaria in March bloom: a saturated, slightly red-shifted deep purple-blue with the satiny finish of a five-petaled cup. Cooler than amethyst, warmer than indigo, with the Mediterranean-garden weight of a flower painted in Persian miniature and Italian fresco alike.

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.
