What you've done is very on trend. I agree with you that it is a lot of white, but if you look at the pictures on Houzz of kitchens, there are a lot of all white kitchens. It looks like the kitchen is open to the family room or great room, so you have an opportunity to have more color there. You can do something interesting with bar stools, and you can place a colorful accessory on the counter in the bar area. The advantage of white is that almost anything goes with it.

Wait till you start adding kitchen things it won’t be so white

Your kitchen is so beautiful! Once you move back into it, try placing nice trays or cutting boards around to see what colors pop for you. A ceramic crock near the stove can hold often used utensils. Your mixer and coffee maker will add more color. Hand towels, a plant or 2…. Unbox your kitchen items to see what speaks to you. What counter stools are you using? Pendants for the island? And what’s on the other walls? Do you have space for some art or can you hang some plates or platters from your China?

You might consider covering the hood vent with cabinet doors painted the same color gray as your island.

You could add some colorful cast iron trivets to your backsplash as decoration even if you don't anticipate using them and/or add other colorful accessories.

You could paint a knife rack or board with cup hooks or spice shelf any color you want.

You could add pressed metal wine related wall sculpture to the backsplash or cabinet doors over your wine rack or your short blank wall to the left of the wine rack -- and you could paint them you favorite bold color -- perhaps even a deep red wine burgundy .

if you want to consider more "pressed metal wall sculpture art" with another "subject", include the specific subject in your search line ... for instance garden or flower or beach or mountains or ranches or farms ... etc.

You’ll be fine - don’t mess with the backsplash. The key to toning it down will be to add some natural elements. A wood bowl with oranges in it, some flowers, or maybe a basket somewhere, a wooden cake stand - that type of thing. It will make a big difference.

Thank you all for suggestions. My chairs are a warm leather, my pendants are a simple modern black cone shape with a bit of bamboo. Once I wainscot and paint gray the front of the island I am hoping it will add more contrast. The quartz top has a simple gray veining that you can't see in the picture. The back splash is a matte white and really doesn't blend well-mostly because it is so flat and artic!!!! Has anyone stained grout? Thinking a light gray?

And if I do decide to add a few windows on cabinets, I'm thinking the 2 on the wine bar side and maybe the thinner, single one on the oven? Just asking. TIA

Sure, you can stain the grout and the light gray would be perfect. Just some little twist without forgetting your initial taste.

About adding the widows on cabinets, I would suggest you choose naturally blending pieces of art.

Your kitchen is beautiful❣️When you start adding items on your countertop, colorful kitchen towels, and a colorful sink mat, it will balance out your pristine and lovely white kitchen.

It will be lovely once you add some accessories. And lucky you, you have countless colors or wood accents to choose from. Right now your eye needs to get used to it . This initial “shock” happens to even those of us who have several homes or remodels in our history .

yup, agree with others, accessories will tone the white down.

colorful spatulas, artwork, natural/wooden elements, bowl of lemons or green apples, rugs, bar stools etc...

just pick a color theme and stick with, you don't want a cacophny of color that it takes away from your gorgeous kitchen... add pieces one at a time and evaluate, no rush to 'get it all done TODAY' :) enjoy the ride !!!

The chairs and light fixtures you describe sound great and will definitely make the room not look stark.

I would encourage you to bring some more wood tones into the bar area. You could pull from the color of your flooring, there is so many options fluting, paneling, ect. This would bring a little more warmth and texture into the space making it not so cold
