Brooding Boysenberry
Brooding Boysenberry (#5C238E) is a true indigo 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 (272°, 60%, 35%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
The adjectival use of brood in the sense of to dwell on — a gerund-as-modifier that describes mood more than reflectance. Used as a color word principally in art criticism since the late nineteenth century: brooding sky, brooding portrait. In the engine's adjective grid, brooding sits in the dark-and-quiet end where the hue is present but reads as withholding rather than presenting itself.
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.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
