A background should sit behind the text, not in place of it. This paragraph lies on the tile at its true scale — if it reads without effort, the tile can go under content.
Cream and taupe-grey shapes sit over a muted grey field of fine, fern-like filigree, with dark charcoal rosettes clustered around the centres. Cream lozenges and wedges form arrow-like forms that repeat in a regular grid, so the eye reads rows of ring-shaped medallions linked by small cream diamonds.
