Ironclad Chiton Emerald

English compound iron + clad — referring to the 19th-century USS-Monitor and CSS-Virginia iron-armored warships. As a color modifier, ironclad implies a saturated-and-armored-and-impenetrable quality where the hue carries the visual weight of forged-iron armor-plate. Sits at the bold-and-fortified end of the grid, parallel to fortified and armored.

A chromium-tinged variety of beryl — the gemstone mined from the Cleopatra-era Mons Smaragdus in Egypt, the Muzo deposits of Colombia, and the Sandawana mines of Zimbabwe. Emerald green refers to a high-clarity faceted emerald with strong color saturation: a saturated, slightly blue-shifted green with the gem's signature internal life. Cooler than fern, warmer than teal, with the heraldic weight of two thousand years of royal favor.
