Buttressed Rise Royal

Old French bouterez, thrusting-mass — past-participle of buttress, derived from bouter (to thrust). As a color modifier, buttressed implies a saturated-and-architecturally-supported quality, the deep-rich color of Gothic-Cathedral flying-buttress-and-rib-vault stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and reinforced.

Old English rīsan, to ascend. As a color modifier, rise implies an ascending-and-emerging quality, the visual register of moonrise-and-sunrise ascending-and-emerging horizon-and-celestial-body atmospheric scattering-of-light surfaces under ascending horizon-and-celestial light. Sits at the modifier-and-time end of the grid, parallel to set and sunup 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.
