Regal Boysenberry
Regal Boysenberry (#A5167F) is a true 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 (316°, 76%, 37%) 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
Latin rēgālis, kingly — derived from rēx (king). As a color modifier, regal implies a saturated-and-royal-formality quality, the deep-rich color of British-Coronation-period royal vestment-and-mantle and Imperial-State-Crown regalia. Sits at the bold-and-imperial end of the grid, parallel to sovereign and royal in usage.
A Rubus hybrid — possibly raspberry × loganberry × blackberry — developed by Rudolph Boysen in 1920s California and made famous by Walter Knott of Knott's Berry Farm. The color refers to a ripe boysenberry: a deep, slightly red-shifted dark purple-red with the slight bloom of an aggregate-fruit surface. Cooler than raspberry, warmer than mulberry, with the California-agricultural weight of a fruit that exists primarily as a single popularized cultivar.
