Royal Khmer Indigo

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.

Sanskrit Khmer, Cambodian. As a color modifier, khmer implies an Angkorian-and-temple-complex quality, the visual register of Angkor-Wat-and-Bayon Khmer-Empire hand-built sandstone-and-laterite temple-and-jungle-overgrown-stonework surfaces under Angkor-Wat-and-Bayon Cambodian-jungle-canopy filtered tropical light. Sits at the modifier-and-cultural end of the grid, parallel to toltec 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.
