Personally, I don't think that MSI Carrara Breve quartz is a good option. You have knotty pine + real slate floors = cozy lakeside cabin (I assume lakeside based upon the photo on the wall).

Your multicolored slate flooring has rich earthy tones (rusts, charcoals, and deep grays) that perfectly mirror the natural, rustic appearance of soapstone. Soapstone's deep charcoal tone will help anchor the room - it will pull in the darker shades that are in the slate floor. Soapstone (a natural stone) fits with the architecture of the space vs. fighting it.

MSI Carrara Breve's white background (it may be a warm white - but it still looks pretty white in the photos I've seen) + its delicate faux-marble veining are designed for contemporary or transitional urban/suburban kitchens. Next to the heavy, warm, dominant wood grain of knotty pine, a white faux marble quartz will look "plastic" and artificially bright. It seems like it will disrupt the home's organic, cozy aesthetic.

Here is a photo of a Houzz user's kitchen with Carrara Breve quartz .- her cabinets are painted BM Simply White + she has a walnut island.

You could also use a leathered black granite - slabs like Absolute Black, Black Mist, or Negresco in a leathered finish will provide a deep charcoal-to-black color with a subtle, dimpled texture. It mimics the organic, historic feel of soapstone. You could also go with a honed finish if you don't want a leathered one.

Agree with danni--white is not a good choice for your kitchen, especially if you're not changing the flooring or the cabinets. What's wrong with what you have? And exactly what is it?

If you want quartz to work with your cabinets and flooring, you need to choose a warm color, in a medium to dark tone. Too light is jarring, a warm gray or brown would work best.

Agree white is not a good choice, nor is anything highly polished.. Asoft green granite would go beautifully in here IMO, or leathered Steel Grey. Steel Grey is considered a budget granite, and when it's leathered it's more of a soft charcoal rather than a deep color.

Or, something like this cream stone with movement (sorry, don't know what it is), although it probably is too busy against your floors -- something along these lines with less movement is what I'm getting at:

Thanks for confirming that white is not it!!! We currently have laminate and it is starting to pull so thought it would be a good time to bring in something else. I will continue to look.

A honed or leathered Virginia mist granite would be a good bet.

Costa Esmerelda is a beautiful green granite and could work if the slab is a color that works with your floor.
