Dark Alexandria
Dark Alexandria (#56306F) 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 (276°, 40%, 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 deorc, dark, gloomy — cognate with the German dunkel and the Latin terra, earth, both pointing to a base meaning of covered or obscured. As a color modifier, dark sits on the lightness axis only: it says nothing about hue or saturation, only that the value is low. Used across every adjective bucket the engine routes to when L < 0.40.
Hellenistic Egyptian capital founded by Alexander the Great (332 BCE) — the Library of Alexandria's parchment dye works produced Tyrian purple manuscript-binding leather for the imperial Roman library. Alexandria color refers to a Library of Alexandria-bound Tyrian parchment fragment: a saturated, slightly cool deep violet with the matte finish of multi-bath Murex shellfish dye on tanned Egyptian goatskin.

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.
