Ominous Burgundy
Ominous Burgundy (#420F10) is a deep red 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 (359°, 63%, 16%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin ōminōsus, full of foreboding — derived from omen. As a color modifier, ominous implies a deep-and-threatening atmospheric-foreboding quality, the dark cool-gray of Goyaesque storm-laden sky. Sits at the deep-and-threatening end of the grid, parallel to foreboding and menacing in tone.
Named for the wine region of east-central France — specifically the Pinot Noir of the Côte de Nuits, aged in oak. The color is a deep, slightly brownish red, darker than wine and softer than maroon, with the dusty surface a young Burgundy develops on the rim of a glass. Adopted into English fashion vocabulary in the late nineteenth century and never displaced.

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.
