Victorious Akkad Indigo

Latin victōriōsus, of victory — derived from victor (winner). As a color modifier, victorious implies a saturated-and-celebratory-and-conquering quality, the deep-rich color of Roman-Imperial victory-procession purpura-dyed paludamentum cloak. Sits at the bold-and-celebratory end of the grid, parallel to triumphant and conquering.

Akkadian Akkadu, Akkad. As a color modifier, akkad implies a Sargon-and-Mesopotamian-Empire quality, the visual register of Akkadian-Empire-of-Sargon hand-built ziggurat-and-cuneiform-tablet bronze-age Mesopotamian-Imperial surfaces under Sargon-of-Akkad Mesopotamian Imperial-cuneiform sun-baked light. Sits at the modifier-and-cultural end of the grid, parallel to sumer and median in usage.

Indigofera tinctoria, the South Asian legume whose leaves yield the deep blue dye that has clothed humanity for at least four thousand years — Egyptian linen, Mayan textile, the slave-grown plantations of Carolina. The color refers to a freshly indigo-dyed cotton thread: a saturated, slightly violet-shifted deep blue with the slight lustre of a fiber surface oxidized in air. Deeper than cobalt, cooler than royal.
