Ironclad Cycle 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.

Greek kýklos, circle / cycle. As a color modifier, cycle implies a repeating-and-circular-time quality, the visual register of seasonal-and-lunar-and-astronomical repeating-and-cyclic period-marker celestial-and-natural cycle-and-rhythm surfaces under repeating cyclic-and-seasonal light. Sits at the modifier-and-time end of the grid, parallel to phase and year 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.
