Hi Marguerite. Those look like nice slabs. Here's a pic showing it against green. I see it as greenish gray. SW Dorian Gray goes well with it. We have had it installed for 2.5 years and it is still perfect - no chips, stains or etches and we use our kitchen heavily. I am very happy with the durability. Some have asked if it is marble as my island has a lot of white marble-looking areas. Remind your fabricator to seal the inside of any holes as our soap dispenser hole developed a shadow around it right after it was installed. We removed the dispenser, let it dry out, and then sealed it. Since then, no issues.
