here is a pic I found. The counter top will be replaced with a dark brownish color. The appliances will also be replaced with either stainless steel or the darker stainless steel. The wallpaper is no longer there. The part above the cabinets will be painted a different color than the cabinets.

Did you paint sample boards? Lay them down on the floor and see which looks best with the tile in your lighting. That's your fixed element to accommodate.

here is a picture of the tile I'm using for the backsplash

Sorry, I looked in your OP to see if you mentioned that and missed it in the later post. Don't go with black stainless. The finish is likely to be discontinued and if it gets scratched, it's not repairable.

We did Alabaster cabinets, agreeable gray walls and extra white trim. This is a small condo kitchen.

Is it possible to see the counter you plan on with the floor, proposed backsplash tile, and the paint color for the cabs? I think that backsplash tile is just going to overwhelm the space with brown especially with “brownish” counters. I envision this mass of brown in the middle of your kitchen, worried that the backsplash is too heavy looking and dark with the counters.

something like this. maybe not so much of a swirl. something a bit more subtle. either light like this or much darker

Have you looked for lighter colored backsplash tile that goes with the cab color? Most people that are regular contributors would suggest waiting to pick your backsplash until cabs and countertops are installed so one can see the whole effect of a paticular tile in the room.

I would try matching a tile to the lightest color in the stone. You need to pick your stone and then try backsplash tiles. The backsplash tile you posted is fighting with the pattern/color of the countertops you showed. The best piece of advice I got when planning my remodel was “One star to a kitchen.” That “Star” is usually the countertop when using a natural stone with pattern. Your choices need to harmonize.
