The same color as the field tile

Hello and thank you for your comment. What is considered field tile? The floor tile is actually pretty close in color to the walls. Are you referring to the lighter tile by the tub?

The field tile is the beige tile. Try propping a cabinet drawer or door next to the bathtub's beige tile, then take some photos with the curtains open and the lights on.

I see a gray/blue diamond in the center of the tiles in the tub/shower area. Would a lighter shade of that color work? What color is the cabinetry? That might look good if painted to match those tiles too. Sample, sample, sample in good light. Have you changed to LEDs yet?
