Knightly Hibiscus

#a30d11
Notes

Knightly Hibiscus (#A30D11) is a true red 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 (358°, 85%, 35%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Knightly
adjective

Old English cniht, young man / knight — adjectival suffix -ly. As a color modifier, knightly implies a saturated-and-chivalrous-and-medieval quality, the deep-rich color of medieval-English-and-French knight-and-squire armorial-bearings-and-livery tradition. Sits at the bold-and-chivalrous end of the grid, parallel to gallant and cavalier.

Hibiscus
noun

Hibiscus rosa-sinensis — the showy mallow of Pacific gardens, the Hawaiian state flower, the source of the deep red sorrel tea sold across West Africa as bissap. The color refers to a fully open hibiscus petal at midday: a hot, slightly magenta red with the velvet texture of a single-day bloom. By evening the same flower has wilted; by morning it's gone.
