There are plenty of cool/warm backsplashes out there to make it all look intentional. What style are you looking for??

Suggest you bring the actual products into your kitchen. Sample of flooring and backsplash.

From what I can tell, the flooring would likely work, but need to see a photo of the backsplash, preferably in your kitchen.

Who can say? Hardware will not change the look of the tops. We have no clue what the tile splash already selected IS? Other than it is "white, gray and silver".

You're showing pictures in near darkness, in what seems to be a very UNDER lit kitchen.

From what I see? Change the tops to black. Or......re think the backsplash. At the very least, you need more lighting , and it should include under the cabinet,

Thank you so much for your comments. I’ll look for a backslash that has a warm tone or both a warm and cool tone. The backslash I chose is still in transit, but I plan to return it. Thank you for the advice on lighting. The kitchen is dark because there is a problem with the ceiling wiring, so I can’t turn on the kitchen light yet. I'll update once I choose the backsplash tile. Again, thank you so much for the advice.

At least change the bulbs you have to LED 4000K and also the rest when the wiring is fixed. I would look for a mixed tile of warm and cool colors and you will needt o go to tile shops and bring home samples this is not a thing to shop for online.

Picking your floor or backsplash tile before getting the lighting fixed is not a good idea. Do the lights first.

It’s fine to get samples of tiles but without the permanent light arrangement in place, everything is being seen “incorrectly”.
