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.
Interlocking star-like floral motifs in teal, grey and lavender sit against a deep blue ground, with small eight-pointed star cutouts and diamond voids framing each cluster. The motif recurs in a regular grid, with each unit mirrored across its neighbours so the flower forms align into diagonal lanes and open rows of blue star shapes.
