Strobing Catalina

#f37bc9
Notes

Strobing Catalina (#F37BC9) is a soft magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (321°, 83%, 72%) places it in the highly saturated band at a light 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

Strobing
adjective

Greek stróbos, whirling — present-participle of strobe. As a color modifier, strobing implies a saturated-and-pulse-flashing quality, the bright color of concert-strobe-light and photographic-strobe high-frequency-pulse light emission. Sits at the bright-and-flashing end of the grid, parallel to flashing and pulsating in usage.

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
