Composed Grace Royal

#3d66dd
Notes

Composed Grace Royal (#3D66DD) 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 (225°, 70%, 55%) 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

Composed
adjective

The past participle of compose, to arrange together — used as a color modifier for hues that read as deliberate and balanced. Composed black, composed gray: the saturation is moderate, the hue is calmly positioned without aggression. Sits at the bold-and-quiet edge of the grid near settled and resolute.

Grace
modifier

Latin gratia, favor-or-thankfulness. As a color modifier, grace implies a flowing-and-elegant-and-blessed quality, the visual register of Botticelli-Three-Graces-and-Apollonian-grace hand-flowing-and-elegant-and-blessed Botticelli-Three-Graces-and-Apollonian-and-Renaissance-classical graced-and-flowing-and-elegant-and-blessed surfaces under Botticelli-Three-Graces-and-Apollonian-and-Renaissance-classical chiton-and-laurel-wreath-and-fountain Florentine-pavilion-light. Sits at the modifier-and-mood end of the grid, parallel to charm and bliss 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.

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.
