Bold Soldanella

#b365df
Notes

Bold Soldanella (#B365DF) is a true indigo with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (278°, 66%, 64%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bold
adjective

Old English beald, brave, courageous — a quality word that crossed over to color in the late seventeenth century. Bold describes a color that asserts itself: high saturation combined with mid lightness, where the hue presents itself without compromise. Sits at the center of the bold-bucket grid, near strong and rich. Closer to a presence word than a pigment word.

Soldanella
noun

European alpine snowbells (Soldanella alpina) — small alpine perennials whose fringed bell-flowers emerge through the spring snowmelt across the Alps and Carpathians. Soldanella color refers to a fully opened Soldanella alpina fringed bell-flower: a saturated, slightly cool deep violet with the velvet finish of finely fringed bell-corolla. The genus name comes from the Italian soldo (small coin), after the round-leaf shape.

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.
