Once you decide on a backsplash, you will need to remove the short existing backsplash to install the new one.

Hard to say since my monitor isn't showing a good choice with both the counters and cabinets. The sample on the far right in the photo with the stove seems closest.

Yes, do remove the current 4" backsplash.

I like area rugs in my kitchens. I use Persian style runner rugs selected to coordinate with the counter or wall color. My own kitchen is white with white/gray/green/black granite and the same granite for the backsplash. The walls are painted to match the bit of green in the granite. The runner rugs have a green background with a Persian design in black, white, tan, and blue.

I don't think any of those tiles are going to brighten your kitchen.

Are you going to repaint? The yellow wall paint isn't the best complement for the gray tiles you are picking.

Do you have any local tile stores, that are not Home Depot or Floor & Decor? You might want to look for slightly larger tiles and not these mosaic sheets.

I really like that fishtail/leaf tile. I don’t know if it’ll brighten anything, but it’ll certainly attract attention.

behind stove is a stick on sheet which will be removed. quartz counter have bit of sparkle Chips.

I think we are confused. You already have a bright and airy kitchen. I think you just would like to add a focal point with the backsplash.

I agree that maybe the paint color is too yellow, but maybe that is just on our monitors.

Even though your counter is speckled, it reads pretty neutral. You certainly can choose a fancy tile.

I’m just not a fan of what you are showing, but I like the idea of bling.

I also agree with everyone about removing the 4 inch backsplash and not tiling above it.

Wow--I love the same tile as Katie B, but I'm imagining it a sophisticated city high-rise. Can't see it with country pumpkins and utensil crocks. I couldn't find pics of it installed, but this chevron is similar:

The only one that goes is the one on the far right when at the stove. The gray's are not working at all with your warm floors.

The last tile on the right looks like it might have some brown in it? I might go for that one.

i don’t think your wall color is too yellow.

I don’t know what you mean by brightening your kitchen. It is already pretty much all bright white. Lighting. I don’t know if you need more lighting.

But if you mean you want more warmth in your kitchen - definitely don’t take out the yellow. Personally, I would be looking to add more of it.

Look at some of the mother of pearl backsplashes. Some have more brown than others, which might work out nicely if your wall is yellow as it appears in some photos (and it seems quite white in others so who knows?).

I agree with Sabrina and others that say “you already have a bright kitchen” and now just pop it with some interest. As Sabrina shows in her picture choose a color subway tile. Sabrina’s blue would look great but notice the island counter in her pic has color.
SO...pop your kitchen with a color on the backsplash!
Choose a color from a nearby rug, sofa, or something as a starting point. Get subway tile samples in colors you like, then take it to a paint store (I love our Benjamin Moore store. Very experienced and knowledgeable staff who know color. Bring these photos and they will make your life sing 😊

The paint color is builders grade which I’ll change in future. everytile i picked in the store looks more warm in actual kitchen.

something which reflects light. I like glass on sides and accent in the middle. These i dont know which ones.

This is so far winner but its very expensive $99/sq ft

Wow to the price, too. Here's one with marble and MOP, but less than half the price:

Another marble and MOP, 24.99/sf

I wouldn't do an accent in the middle for several reasons. First, they are really out of style and second, you have a regular 30 inch range with a back to it. Accent tiles are not used with those kinds of stoves. I love the tile Mama Goose pictures above.

I learned that marble stain easily and needs to be sealed often.

i cook alot of food and all worried about water and food stains.
