   Warm plaster and clay, not the dark-charcoal-plus-gold combo
   every AI-generated "premium furniture" site defaults to.
   Base is a chalky lime-plaster off-white; ink is a soft near-
   black with a hint of green rather than pure black; the accent
   is a burnt terracotta instead of brass/gold.
