@Anna I love the colors! I have simply white in my house and went with white Dakar quartzite but can find very few posts with white Dakar. Your kitchen looks gorgeous!!

Imcutnup: Oddly, the only thing that has stained my leathered quartzite has been strawberries. Red wine, red vinegar, hibiscus tea, turmeric, paprika—nothing has stained it—except the strawbwrries. Quartzite doesn’t etch from acids such as pickle juice, vinegar or lemon juice because unlike marble, there’s no calcium in quartzite.

I'd recommend choosing the counter that works with the less changeable components like your cabs and floor. Then find a backsplash. At that point you can find the correct wall shade of white. For the counter that means securing the actual slabs because they'll vary being a natural product. And checking the tones in your space with your lighting. Help! Mont Blanc VS Monte Blanc. Are either real Quartzite? (houzz.com) Take a sample card of the white with you.

I have a cream colored quartz counter on my sage green vanity. I think blue or green could work for your vanity color❣️
