Bold Echinacea

#910574
Notes

Bold Echinacea (#910574) is a deep magenta 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 (312°, 93%, 29%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

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.

Echinacea
noun

North American purple coneflower (Echinacea purpurea) — a midwestern-prairie Asteraceae perennial with deep-magenta drooping ray-flowers and a prominent rust-orange disk-cone center. Echinacea color refers to a fully opened Echinacea purpurea ray-flower in late-summer light: a saturated, slightly cool deep magenta with the velvet finish of fresh drooping ray-flowers. The Greek genus name echínos (hedgehog) refers to the prickly disk.

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.
