I see no reason to paint those cabinets white. They look nice. It’s your backsplash that is the problem.

Then change the granite counters which you said you weren’t doing, so I didn’t suggest it initially. The cabinets look nice, they’re not the problem. It will cost you as much or more to paint the cabinets as to change the counters, unless you hire a hack to do paint, and then you will not be happy with that result, and still have the counters to contend with.

Looking at the photos I agree with M Miller that the backsplash and counters do not seem to go together. If it were me I would change the counters and leave cabinets as is. Good luck!

I love granite counters, but not in this kitchen. Granite--both what you have and any other granite you might replace it with--is too busy with your backsplash. Your backsplash, since it is new and you love it, must govern what you choose for counters. Counters need to be quiet with no pattern. You can find that in quartz or Corian. Do not paint your cabinets, they are pretty the way they are. Painting might look nice for now, but in a year or two you run the risk of chips and bleed-through. Not worth it when they are pretty the way they are now.

You might want to consider hiring a designer on an hourly basis to help you choose a color of counter. Limit the scope of work for the designer to just that, so that the fees don't run up more than what you need to do. We can't help you choose over the internet because each monitor shows color differently. You can go with a designer to a quartz showroom, bringing with you a sample of your backsplash and a cabinet door, and s/he --who has a trained eye -- will help you choose which color counter would be best.

Agree with the others. White will make your counters and backsplash look harsh and will not work with them. The cabinets you have now soften the backsplash. Pick a color from the backsplash in quartz for your counters.

There are quiet granites, but they tend to be darker; which might work well with your gray walls & gray in backsplash. Steel gray & Virginia Mist are two that come to mind immediately but there are others.

Why do you want to pull your counters out. Pick the oval backsplash like you have in white or cream and let the grout show. It will be a similar effect. So you can love it. The existing backsplash doesn't work but that needs swapping not a full counter rip out.
