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.
Sage-green scalloped rosettes sit on a mint background, each with a small pale star-like opening at center, alternating with pairs of dark slate lobed blobs and small leaf-shaped ovals placed between them. Motifs repeat on a regular grid, with the rosettes and clusters forming diagonal rows that give a steady, rhythmic lattice across the field.
