Affable Tartarus
Affable Tartarus (#190C16) is a deep magenta 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 (314°, 35%, 7%) 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
Latin affābilis, easy-to-speak-to — adjectival suffix -able. As a color modifier, affable implies a neutral-and-friendly-and-approachable quality where the hue carries the visual register of Edwardian-and-American-Country friendly-and-welcoming-hosting interior-decoration-and-textile coordinated-color tone. Sits at the neutral-and-friendly end of the grid, parallel to amiable and cordial in usage.
Greek Τάρταρος, the deepest pit — the abyss beneath Hades itself where Zeus imprisoned the Titans after the Titanomachy. Tartarus color refers to the deepest cave of an Attic 5th-century BCE katabasis vase-painting: a saturated, slightly cool deep black with the matte finish of carbon-and-iron-tannin pigment on red-figure-style fired Attic ceramic. The deepest stratum of the Greek underworld cosmology.

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.
