Stygian Soldanella
Stygian Soldanella (#331A3F) is a deep violet 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 (281°, 42%, 17%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
From the Greek Styx, the river of the underworld — used as an adjective in English since the seventeenth century to mean infernally dark. Stygian is the literary register for absolute darkness, deeper than inky and warmer than vantablack. Almost always reaches for poetic weight rather than precise reflectance.
European alpine snowbells (Soldanella alpina) — small alpine perennials whose fringed bell-flowers emerge through the spring snowmelt across the Alps and Carpathians. Soldanella color refers to a fully opened Soldanella alpina fringed bell-flower: a saturated, slightly cool deep violet with the velvet finish of finely fringed bell-corolla. The genus name comes from the Italian soldo (small coin), after the round-leaf shape.

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.
