Grim Carthage
Grim Carthage (#542C71) 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 (275°, 44%, 31%) 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
Old English grimm, fierce / fierce-faced — sharing root with German grimm and Old Norse grimmr. As a color modifier, grim implies a deep-and-cool-and-comfortless-formal quality, the dark cool-gray of Norwegian-fjord mid-winter atmospheric-overcast light. Sits at the deep-and-cool end of the grid, parallel to bleak and stern in atmospheric register.
Phoenician colonial capital on the Tunis coast (founded 814 BCE) — and a major secondary Tyrian purple production site supplying the western Mediterranean trade network. Carthage color refers to a Carthaginian trade-textile fragment from the Byrsa hill citadel: a saturated, slightly cool deep violet with the matte finish of multi-bath Bolinus brandaris shellfish dye on hand-loomed Punic wool.

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.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
