Dominant Crinoline

#a4188e
Notes

Dominant Crinoline (#A4188E) is a true violet with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (309°, 74%, 37%) 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

Dominant
adjective

Latin dominārī, to rule — present-participle of dominate. As a color modifier, dominant implies a saturated-and-leading quality where the hue claims visual precedence over neighboring colors in the surrounding palette. Sits at the bold-and-imperative end of the grid, parallel to commanding and authoritative.

Crinoline
noun

French crin, horsehair — Originally a stiff horsehair-and-linen petticoat fabric, the term crinoline came to refer to the cage-and-hoop dress structure of the 1850s–60s. The deep-magenta fuchsine-dyed crinoline silk was the dominant Belle-Époque colour. Crinoline color refers to a Worth-period crinoline-skirt silk faille: a saturated, slightly cool deep magenta with the silky finish of fuchsine-dyed jacquard-figured Lyon silk.

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.
