Authoritative Soldanella

#b13bda
Notes

Authoritative Soldanella (#B13BDA) is a true violet with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (285°, 68%, 54%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Authoritative
adjective

Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.

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.
