Pure Meteor Ultramarine

#1664d5
Notes

Pure Meteor Ultramarine (#1664D5) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (215°, 81%, 46%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary amber. 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.

Meteor
modifier

Greek μετέωρος, suspended-in-air. As a color modifier, meteor implies a streaking-and-burning-and-shooting-star quality, the visual register of Perseids-and-Leonids-meteor hand-streaking-and-burning-and-shooting-star Perseids-and-Leonids-and-Geminids-meteor meteor-and-streaking-and-burning-and-shooting-star surfaces under Perseids-and-Leonids-and-Geminids-meteor August-and-November-and-December-night-sky shooting-star-light. Sits at the modifier-and-cosmic end of the grid, parallel to comet and nova in usage.

Ultramarine
noun

The pigment ground from lapis lazuli — the Afghan mineral imported through Venice in the late Middle Ages, more expensive by weight than gold during the Renaissance. The color refers to a freshly mixed ultramarine pigment in linseed oil: a saturated, slightly violet-shifted deep blue with the matte finish of micron-ground rock. Deeper than cobalt, cooler than royal, with the art-historical weight of the blue Vermeer reserved for Mary's robe.

Wide gamut

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.
