Replete Atlas Royal

#364cc3
Notes

Replete Atlas Royal (#364CC3) is a true blue 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 (231°, 57%, 49%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Replete
adjective

Latin replētus, filled — past-participle of replēre. As a color modifier, replete implies a saturated-and-fully-pigmented quality where the hue is completely loaded with its source pigment. Sits at the bold-and-saturated end of the grid, parallel to brimming and suffused in usage.

Atlas
modifier

Greek Ἄτλας, Titan-bearing-the-heavens. As a color modifier, atlas implies a Titan-bearing-heaven-and-globe-bearer quality, the visual register of Farnese-Atlas-and-Titanomachy-Atlas hand-Titan-bearing-heaven-and-globe-bearer Farnese-Atlas-and-Titanomachy-Atlas-and-Hellenistic-marble atlas-and-Titan-bearing-heaven surfaces under Farnese-Atlas-and-Titanomachy-Atlas-and-Hellenistic-marble Naples-museum-and-celestial-globe globe-bearer-light. Sits at the modifier-and-myth end of the grid, parallel to titan and zeus in usage.

Royal
noun

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.

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.
