Sable Eustoma
Sable Eustoma (#192149) is a deep blue 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 (230°, 49%, 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Martes zibellina, the Eurasian sable — a small mustelid of Siberian taiga whose deep brown-black fur was the most prized mammalian pelt of the Russian and Chinese imperial courts. The color refers to a fresh sable pelt: a deep, slightly warm near-black with the satin finish of densely packed guard hairs. Warmer than ink, glossier than coal, with the courtly weight of a fur reserved for tsars and emperors.
Mexican-Texan prairie gentian (Eustoma grandiflorum) — marketed worldwide as lisianthus, a long-stemmed cut-flower industry staple with deep-violet rose-form blooms. Eustoma color refers to a freshly cut Eustoma grandiflorum fully opened bloom: a saturated, slightly cool deep blue-violet with the velvet finish of overlapping ruffled tepals. The Greek genus name eu-stoma means fine-mouthed, after the wide-throated corolla.

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.
