Armored Murex
Armored Murex (#73259E) is a true indigo 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 (279°, 62%, 38%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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 French armëure, armor — past-participle of armor, derived from Latin arma (weapons). As a color modifier, armored implies a saturated-and-armor-clad-and-defensive quality, the deep-rich color of medieval-knight full-plate-armor visible-and-formidable battle-presence. Sits at the bold-and-fortified end of the grid, parallel to ironclad and shielded.
Bolinus brandaris and Hexaplex trunculus — the two principal Mediterranean sea-snail genera whose hypobranchial-gland secretion was processed into Tyrian purple dye for two-and-a-half millennia. Murex color refers to a freshly Murex-dye-bath-emerged Phoenician trade-textile: a saturated, slightly cool deep violet with the matte finish of multi-bath shellfish-dye on hand-loomed Levantine wool. The Latin murex gives English murexide, a synthetic violet-red dye.

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 is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
