IMO - no.

^^^same^^^

Big NO.

Sorry, no; too busy.

The Ironsbridge might work. Would need to see the overall space and a larger view of the countertop. I wouldn't select the backsplash and countertop without knowing which cabinets you're going with. Slow down if you can, keep working on the selections as an entire design.

No. No. No. In addition? I would avoid all the "relief" tiles unless you want a scrub brush dangling permanently from your hand.

Back splash is BEST selected after a fully installed counter goes into place.

You said....

"Haven't decided on cabinet color or stain yet, but cabs will definitely not be white. Will probably be using Cafe white matte appliances, or GE Slate as a distant second choice."

What is the flooring??

I would stay FAR, FAR from slate appliances destined to become the harvest gold or avocado of yesteryear, and know that stainless appliances are your most f.o.r.e.v.e.r finish, allowing a mix of brands and easier replacement in a fail of one appliance up the road. Same is truth on sinks. A good stainless is equally forever.. Sorry - truth. White "Cafe" apps are best with WHITE cabinetry, or a very pale white oak. Otherwise the result is a nervous looking,jumpy kitchen. Can only advise: )

Most important before ALL of this is your layout and work flow. .......and all of this pecking order in decisions, matters greatly.

Although the tiles you show are pretty, the cabinet color and counter top should be selected first, then backsplash last. Make sure you see a large piece of the quartz before you order it. The Ironsbridge has large, prominent, fake looking veins and is very bossy. I would advise against any quartz that tries to mimic stone with dramatic veining. It always looks fake.

@Diana Bier Interiors, LLC Thank you for the comment on Ironsbridge. I've seen a large sample, but not a slab. I actually had my design all worked out, only to have Cambria discontinue my first and second choices. So I am back to the drawing board with design choices I'm not terribly crazy about. As much as I love Cambria, it seems they are determined to produce these sort trendy designs.

I always recommend either caesarstone London gray or Silestone Lagoon. Both are subtle and neutral. You should check them out
