You already have a backsplash with the 4” riser. So I don’t think that functionally, or aesthetically, peel and stick will add anything to the space.

Grey for wall color is for the most part over. Plus, in this case, the grey is not doing anything for the space. Try a sample of BM Ballet White for the walls and trim.

Also, if possible put your lights on dimmers. And maybe add some wood cutting boards and plants.

Second the no second back splash piled on. The "easiest" impact would be to change the wall color. It's yellowing your cabinets. It's unfortunate the trim and cabinets don't match. I don't see muddying up the trim as being a satisfactory fix.

I’d be tempted to bring a cab door to Ben Moore or a Sherwin Williams and get it paint matched and them see how the wall looks in that color.. it might work fine with the whiter trim

It's the gray that's the odd man out, not the trim. The grey is clashing with the cabinets and the floors. White trim with slightly darker walls is a nice, fresh look. (Chat gpt helped with this.) It would look better if the cabinets were white as well but this is an improvement over the gray walls, IMO.

Add a little white around the room (a print for the wall with some white, white fruit bowl, etc.) and some natural elements (wood stools, a basket of succulents) and it should all come together.

Another person who thinks that the gray is the problem. Get a match for the cab color and then go a tad or two lighter for the new wall color. The white trim will likely be just fine. Or certainly a lot easier to live with than it is now with the gray walls.

Agree with both above comments. @deegw gave you a perfect example of how the right ivory will pull the room together.

Your 4” granite piece IS your backsplash. Do not add more tiles above it. If you want another backsplash you need to remove that 4” piece so the new tiles go down to the horizontal part.

Paint the ceiling too.

As mentioned by others, it's the gray walls that don't work with the cabinets. Here's a cream kitchen with cream walls and blue accents...

I asked Chat GPT to add some accessories, I think it turned out pretty good! A new light would look good too.

That looks good @deegw . And I like the idea of the wood stools. Rove Concepts has a nice stool called the Aubrey.

A bit pricey but a nice style; there are also similar styles from other vendors such as Amazon.

So as I mentioned upthread, you see how the current grey walls are not helping the space. Warm white walls are much better. This is why I suggested BM Ballet White; it’s a warm white that I think could possibly work in your space. Or you could alternatively choose another warm white. You would need to test the colors. The warm white you use does not have to exactly match your cabinets. If the bright white doors are still too much for you, you could paint them in the same warm white color. Paint all the trim out in that color. That is what I would do. I’d paint everything the same color.

If you really just prefer to have a grey, you need more of a greige... such as BM Edgecomb Gray. You can test that color, too. The grey that is currently on the walls is just too cool. Try Edgecomb Gray. You could use it the same way as a warm white. Paint the walls and everything else the same color... ie walls, doors, trim.

Thank you all for the feedback. I agree about the wall color. I think I have avoided it because that color is throughout the entire floor. The back of the kitchen opens up to the dining room/living room joint space as well as the hallway from the front door and ALL of it is the same gray. I don't know how it would look to paint just the kitchen but leave the rest of the house when there are adjoining walls with different paint colors (if that makes sense?).

And the ceilings. Using an extension for your wall painting with a roller makes it much faster and easier.

You make sense about the color carrying through out an open plan. The trick is trying to change color where walls meet to make corners. And all that trim is the same way but the bright white is so neutral, it will work even with the creamier cabinets. While I am not a fan of the cool grey walls, they pick up some of the stone color. It's the white doors that stick the most to me. I would paint them and walls in a warm shade to go with the cabinets. Warm and cool whites, beige and grey can play well together if they are repeated through out the spaces. and adding decor will take you eye off the paint differences. Bright white porcelain dishware, warm light wood or fibers and greyish metals can tie things together. Art and or calendar on that wall will also make the grey recede. Settle in and live with it a bit before starting the maddening choice of the right warm white.

Warm and cool colors can work together. It’s true.

I suggest you paint the walls, doors and trim in the kitchen Edgecomb Gray.

Here is an article about the color:

https://www.homesandgardens.com/interior-design/ways-to-decorate-with-edgecomb-gray-by-benjamin-moore

You do not need to match your kitchen to the adjacent room; but the Edgecomb Gray will work with the grey next door and will also work with the warmer tones in your kitchen.

Don't touch the trim. Just paint the walls in the kitchen and open dining area of the kitchen a cream that is color matched to the cabinets. If you post a pic of the other side of the kitchen and how that side opens to the living room we can show you where to start and stop the cream paint.

It will not be a problem to see the cream kitchen walls in contrast to the living room grey walls. Just do the walls, don't mess with the trim, and it should all come together. If in the end the trim still really bothers you then address it.

No to adding a backsplash - you already have one.

The walls are the issue the trim is fine but a nice soft grayed/ green on the walls will be a nice way to blend the 2 whites. Then some nice decor on the island and anice piece of art on that wall by the door will make the space feel much better .

You just moved in. Before you decide on specific paint colors I would suggest that you make a plan and create a whole home color palette.

Start with the colors that must stay. This is different for different people, but often includes the items that are expensive or difficult to replace - Flooring, countertops, cabinets, and things that you love - maybe a stone fireplace, your brand new sofa, wood trim . . .

Second step - what colors do you love? Not wall colors - the colors that call to you when you are shopping and make you bring them home. The vase, artwork, pillows, linens . . .

You want your walls to be a beautiful backdrop for all your things.

I have two sisters and we really like different colors and patterns. What works with my things may not work with their things. (Top row represents my colors/style, 2nd row my sister, third row my sister in law).

Once you have both what must stay and the colors you love you can figure out what neutrals will work with both and what white works best with your neutral.

Flooring probably has a greater impact on what wall colors work/don't work than anything else.

You will need to work with the flooring to make sure your whites/neutrals don't go pink, green or yellow next to the flooring.

Be cautious with AI - The AI generated picture is pretty, but it changed all the colors - not just the walls. It warmed up the floors, cabinets, countertop . . . all things you don't want to change.

There are a lot of choices that are not white or neutrals. Mother nature loves green.

I helped my niece create a whole home pallet for her new home a few months back.

She had a navy sofa and a carpet that included blues and soft greens and her dining room chairs had the same soft green color upholstery.

Here are the colors she selected for her home and a picture of the sofa and carpet from her last home.

The blues and greens that she loves are repeated throughout the home (excluding her 2 little girl's bedrooms).

Seeing an example of how a color palette was developed may help you develop your own.
