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.
Radiating star-like rosettes of burnt orange, brown, mauve and olive green fill the field, with spiked wedges fanning out from central hubs and elongated lens shapes running vertically between them. The motif repeats in a regular grid, with rosettes alternating with olive diamonds and vertical bands that create a steady, rhythmic lattice across the page.
