Sumptuous Toltec Cerulean

Latin sūmptuōsus, expensive — derived from sūmptus (expense). As a color modifier, sumptuous implies a saturated-and-rich-and-luxurious quality, the deep-rich color of Burgundy-and-Champagne-Court late-medieval silk-and-velvet livery in the Très-Riches-Heures manuscript tradition. Sits at the bold-and-saturated end of the grid, parallel to opulent and lavish.

Nahuatl Tolteca, Toltec. As a color modifier, toltec implies a Tula-and-Mesoamerican quality, the visual register of Toltec-civilization-of-Tula post-Classic Mesoamerican hand-carved Atlantean-warrior-and-feathered-serpent stone-monumental surfaces under Tula-Hidalgo-and-Chichen-Itza post-Classic Mesoamerican high-altitude light. Sits at the modifier-and-cultural end of the grid, parallel to aztec and olmec in usage.

From the Latin caeruleum, originally referring to dark blue paint pigment of the Roman world, then via French céruléen into English. As a modern art-supply name, cerulean blue is the cobalt-tin oxide pigment introduced in 1805. The color refers to a clean, slightly green-shifted blue with the matte finish of mineral pigment in linseed oil: lighter than cobalt, deeper than aqua, with the painter's weight of a word for sky.
