Yes, we need a better picture of the BS. First, I agree with beeps about the 4" BS. My feeling is to do one or the other, but not both. Your issue is something that I faced with my kitchen. My Dove White cabinets were too white for the browns in my Giallo. I first had a white tile installed, but then removed it. Too white for the browns. My current tile is Grazia Rixi in crema. It works as a transition color between the white in the cabinets and the browns in the counter. Your BS picks up on more of the browns and it slso looks a bit busy with your counter. I would find a lighter toned beige or cream tile without the color variation. I would remove the 4" BS and replace with tile.

It is really easy to search for photos on Houzz. Here is one I found in 5 seconds. Not what I would put in my kitchen, but it works in this modern style. I think the back splash is glass. Not sure it would work as well if you are using more traditional materials.

Hi! Countertops get installed Thursday! I can try to find tiles, and then will post everything once installation of tops is done.

Thank you to everyone who responded, very much appreciate your iput. The owners of the company agreed to replace the counter at their cost and do it correctly - this was achieved only because we could back up our claims of an incorrect install based on the information provided by you all! Sammy - unfortunately, my sister lost her two dogs and cat in the fire; she was not home. The cause of the fire was the slight reverberations of the built-in microwave caused a screw in the mounting bracket to slowly over time rub the the casing off an electrical wire in the wall; the fire investigator had never seen this before and is now using this in their training. She would trade all of her possessions to have her pets back, a year later it's still devastating for her to have lost them. Again thanks to all and hope everyone has a happy, healthy, safe and prosperous New Year!
