Ironclad Sway Crimson

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.

Middle English swēven, to-move-side-to-side. As a color modifier, sway implies a side-to-side-and-rocking-and-rhythmic quality, the visual register of willow-branch-and-tall-grass-sway hand-side-to-side-and-rocking-and-rhythmic willow-branch-and-tall-grass-and-pendulum-clock swayed-and-side-to-side-and-rocking-and-rhythmic surfaces under willow-branch-and-tall-grass-and-pendulum-clock breeze-rocked-and-pendulum-and-cradle riverbank-meadow-light. Sits at the modifier-and-mood end of the grid, parallel to drift and float in usage.

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.
