It's very hard to tell the color of your cabinets by the pictures. Maybe go with a light blue tile for the backsplash & a solid quartz for the countertop. Or maybe a marble look quartz.

I suggest quartz in the white of your cabinets and white glossy subway tiles for the backsplash,

traditional east coast kitchen.

I don't really understand how you could need a "pop of color" if you already have half blue cabinets. Another vote for some kind of white.

Cambria Summerhill, Seagrove or Pendel Hill Would look nice with a white Backsplash

Hello u129003 , we love the navy blue cabinets you've chosen and we would be happy to help you narrow down your search. We recommend checking out our Swanbridge, Torquay, or White Cliff designs. Below are a few examples of pairings we hope will inspire you!

Swanbridge paired with a moody chevron-tile backsplash:

I would definitely add more color. As suggested either do a busy counter with a simple backsplash or a quiet counter with a colorful backsplash. Both would be quite striking and beautiful.

For those saying you already have color in the blue; blue is a neutral so don't worry about adding more color.

I really like the tile posted by kariyava.

Thanks for all the input. Thanks cpartist for backing me up on adding a pop of color. My husband wants to warm the kitchen up a bit and suggested light wood counter tops. I'm worried that might be too much with hardwood floors. Plus it is a small space. Any thoughts?

Thinking about doing this backsplash all the way around space but only 12" up from counter top and painting the rest of the walls.. Any advice on counter tops to keep space airy but soft. Cabinet color Kraftmaid Moonshine for upper and Midnight for lower. The Kraftmaid Midnight color is almost identical to Benjamin Moore Hale Navy paint.
