Earnest Float Royal

#536be3
Notes

Earnest Float Royal (#536BE3) is a true blue with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (230°, 72%, 61%) 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

Earnest
adjective

Old English eornost, seriousness, zeal. Used as a color modifier since the nineteenth century for hues that read as committed but unshowy — the working blues of denim, the deep greens of Quaker meetinghouses. Sits in the bold-and-quiet corner of the grid, slightly less luminous than resolute and slightly less institutional than imperial.

Float
modifier

Old English flotian, to-move-on-water-surface. As a color modifier, float implies a buoyant-and-untethered-and-drifting quality, the visual register of lotus-pond-and-petal-on-river-float hand-buoyant-and-untethered-and-drifting lotus-pond-and-petal-on-river-and-paper-lantern floated-and-buoyant-and-untethered-and-drifting surfaces under lotus-pond-and-petal-on-river-and-paper-lantern Heian-and-Edo-and-Yangtze still-water-light. Sits at the modifier-and-mood end of the grid, parallel to drift and hover 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.
