Post a pic so we can see what you see...

color is shown here. grey island and revere pewter walls.

The Bobdyn cabinets have a yellow undertone to them, so next to a pure white, they will appear more yellow. I would stay away from any tile with white for this reason. Since you would like a fresh, beachy feel, I would utilize a glass tile in a grey tone from your counter top. The counter top appears to have grays with a blue undertone, so I would select a gray glass tile with a blue undertone as well so that it coordinates. This kitchen uses a gray glass tile with beige undertones to coordinate with the counter top. You can see the efffect this creates.

These glass tiles would look great with the light colors in your kitchen:https://www.houzz.com/products/aspect-3x6-in-glacier-prvw-vr~40877467. The color is more of an icy blue, so it would pair well with your countertop color!

Realizing this post is a few years old but wondering what you ended up choosing for a backsplash. My cabinets and counter are very similar to yours and I’m struggling to find a tile. Thank you
