Saturnine Akebia
Saturnine Akebia (#2D1D46) is a deep indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (263°, 41%, 19%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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
Latin Sāturnīnus, of Saturn — referring to the gloomy temperament associated with the planet Saturn in classical-and-Renaissance astrology. As a color modifier, saturnine implies a deep-and-cool-and-gloomy quality, the dark cool-gray of Hellebore-and-Lead alchemical-melancholic associations. Sits at the deep-and-cool end of the grid, parallel to sullen and gloomy.
Asian chocolate vine (Akebia quinata) — a deciduous twining vine native to Japan, China, and Korea, with deep-violet five-petaled flowers that release a chocolate-like fragrance in late spring. Akebia color refers to a fully bloomed Akebia quinata female flower: a saturated, slightly cool deep violet with the velvet finish of fused-petaled cup-flower. The Japanese name akebi refers to the pendulous fruit pods.

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.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
