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.
Concentric rings of purple, green, and gold-tinged pastel bands form pairs of oval medallions that interlock across each tile, with small blue and cream diamonds marking the gaps between them. Each repeat sets two rows of paired ovals in a steady grid, so the eye reads a rhythmic lattice of nested loops rising and falling across the page.
