Composed Catalina

#b70d9a
Notes

Composed Catalina (#B70D9A) is a true 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 (310°, 87%, 38%) places it in the highly saturated band at a mid 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

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.

Catalina
noun

Californian Catalina silver lace (Eriogonum giganteum) — a Polygonaceae shrub native to Santa Catalina Island off the southern California coast, with deep-magenta clustered terminal flower-heads in late summer. Catalina color refers to a fully bloomed Eriogonum giganteum terminal cluster on the Catalina Island chaparral: a saturated, slightly cool deep magenta with the matte finish of dense small radiating flower-heads.

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.
