Knightly Tarbuttite
Knightly Tarbuttite (#7280F2) is a true blue 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 (233°, 83%, 70%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
Rare zinc-phosphate mineral first described from the Broken Hill lead-zinc deposits of Zambia in 1907, also found at Reaphook Hill in South Australia. Tarbuttite color refers to a deep-violet Broken Hill tarbuttite crystal cluster: a saturated, slightly cool deep blue-violet with the glassy finish of zinc-phosphate mineral. Named for Percy Coventry Tarbutt, an early-20th-century mining-company director.
