Substantial Loganberry
Substantial Loganberry (#891162) 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 (320°, 78%, 30%) 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
Latin substantia, substance — adjectival suffix -al, derived from sub-stāre (to stand under). As a color modifier, substantial implies a saturated-and-weighty-and-material quality where the hue carries visual mass and presence. Sits at the bold-and-weighty end of the grid, parallel to weighty and hefty in usage.
Rubus × loganobaccus — a chance hybrid between Rubus ursinus (Pacific blackberry) and Rubus idaeus (raspberry) discovered in 1881 by Judge James Harvey Logan of Santa Cruz, California. Loganberry color refers to a freshly picked Rubus × loganobaccus aggregate-drupe-cluster: a saturated, slightly cool deep magenta with the matte finish of anthocyanin-rich aggregate drupelets. Slightly cooler than raspberry.
