Smothering Boysenberry

#670d55
Notes

Smothering Boysenberry (#670D55) 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 (312°, 78%, 23%) 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

Smothering
adjective

Old English smorian, to suffocate — present-participle of smother. As a color modifier, smothering implies a deep-and-overwhelming-and-pressing quality where the hue is dominated by an enveloping darkness. Sits at the deep-and-overwhelming end of the grid, parallel to suffocating with kinetic register.

Boysenberry
noun

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.
