Sumptuous Glass Royal

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.

Old English glæs, glass. As a color modifier, glass implies a transparent-and-vitreous quality, the visual register of Murano-and-Bohemian-glass hand-blown-and-cut crystal-and-leaded-glass Venetian-and-Bohemian glass-and-crystal surfaces under Murano-and-Bohemian-glass workshop-light. Sits at the modifier-and-texture end of the grid, parallel to gloss and shine in usage.

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.
