Composed Stokesia

#3a31b5
Notes

Composed Stokesia (#3A31B5) 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 (244°, 57%, 45%) 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 yellow. 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.

Stokesia
noun

North American Stokes' aster (Stokesia laevis) — a southeastern-coastal-plain Asteraceae native cultivated as a ground-cover perennial with fringed lavender ray-flowers. Stokesia color refers to a fully opened Stokesia laevis flower head: a saturated, slightly cool deep blue-violet with the velvet finish of finely fringed ray-flowers around a paler central disk. Named for Jonathan Stokes, an English physician-botanist of the 18th century.

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.
