Sinewy Mǔdan

#901175
Notes

Sinewy Mǔdan (#901175) 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 (313°, 79%, 32%) 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

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.

Mǔdan
noun

Chinese 牡丹, peony (Paeonia suffruticosa) — the King of Flowers in Chinese tradition, with deep magenta double-petaled cultivars cultivated since the Tang dynasty for imperial gardens. Mǔdan color refers to a fully bloomed Paeonia suffruticosa double-flower: a saturated, slightly cool deep magenta with the velvet finish of densely overlapping ruffled petals. The flower is China's unofficial national bloom.
