There are several backsplash options that would complement white marble countertops, including:

1. Subway tiles: Classic subway tiles in white or light gray would create a timeless look.

2. Mosaic tiles: Small, intricate mosaic tiles in marble or glass would add texture and interest to the space.

3. Herringbone pattern tiles: Tiles in a herringbone pattern would add a modern touch to the space.

4. Solid color tiles: Solid color tiles in a complementing shade of white or gray would provide a clean and cohesive look.

5. Natural stone tiles: Using natural stone tiles, such as slate or travertine, would create a rustic and charming look that pairs well with white marble countertops.

Ultimately, the choice of backsplash will depend on personal style preference, the overall design aesthetic of the kitchen, and the desired level of contrast between the countertops and backsplash.
