Fortified Forged Ultramarine

Latin fortificāre, to make strong — past-participle of fortify. As a color modifier, fortified implies a saturated-and-strengthened-and-defensive quality, the deep-rich color of Vauban-style military-fortification stone-and-earth rampart-and-bastion architecture. Sits at the bold-and-fortified end of the grid, parallel to bastioned and armored.

Old French forgier, to-forge. As a color modifier, forged implies a hand-hammered-iron quality, the visual register of blacksmith-and-armorer-forged hand-hammered-and-tempered iron-and-steel-and-bronze blacksmith-and-armorer-forged surfaces under blacksmith-and-armorer-forge bellows-and-anvil light. Sits at the modifier-and-texture end of the grid, parallel to hewn and cast in usage.

The pigment ground from lapis lazuli — the Afghan mineral imported through Venice in the late Middle Ages, more expensive by weight than gold during the Renaissance. The color refers to a freshly mixed ultramarine pigment in linseed oil: a saturated, slightly violet-shifted deep blue with the matte finish of micron-ground rock. Deeper than cobalt, cooler than royal, with the art-historical weight of the blue Vermeer reserved for Mary's robe.
