Sinewy Cyclamen

#d51c9e
Notes

Sinewy Cyclamen (#D51C9E) is a true magenta with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (318°, 77%, 47%) 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

Sinewy
adjective

Old English sinu, sinew — adjectival suffix -y. As a color modifier, sinewy implies a saturated-and-muscular-and-firm quality where the hue carries the lean-and-strong visual presence of a Roman-statue athletic figure. Sits at the bold-and-firm end of the grid, parallel to stalwart and rugged in usage.

Cyclamen
noun

The genus Cyclamen — the small Mediterranean and alpine perennials whose distinctive backswept petals appear in autumn and persist through winter snow. The color refers to a fresh deep-pink Cyclamen persicum hybrid: a saturated, slightly cool deep pink-magenta with the satiny finish of swept-back petal form. Cooler than peony, warmer than fuchsia, with the cool-weather garden weight of a flower that blooms when most others have gone dormant.

Wide gamut

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.
