In Benjamin Moore, you could try Newburyport Blue (HC155) or, in the new Century collection, either Blue Muscari (U9) or Delft (U0). The Century collection is not available at all Benjamin Moore outlets, but it's worth looking for.

Your kitchen is beautiful! I love the mix of white and wood cabinets with the Hanstone quartz. Thank you so much for the photos! I used this quartz in my bathrooms and this is similar to what I’m planning to do with my kitchen next. I see you continued the quartz in the backsplash behind the stove. What did you use for the backsplash behind the sink and desk? Also, what have you found to work best for maintaining the quartz? I’m a little afraid of mine given the warnings they gave me about heat damaging it. I’ve also noticed that I need to wipe off water spots. Thank you!

@Lisa I do have a question for you! The thing that concerns me about Cambria is the heat comments. I would never put a hot pan on any countertop. BUT what about things like an All Clad Slow Cooker? Moccamaster or Nespresso Coffee maker? Instant Pot? What things like this needs something under them to use? Air Fryer.. I would think Vitamix would be fine? I think it would look awful to always have something under the coffee make or Vitamix. The other things are not kept on the counter. I have never had to use something under them with the granite countertops. I don't Have to go with quartz. If I do go with quartz it will definitely be Cambria. I thought about going with marble but I am a messy cook! I still want to see your blue when I go back to the beach. (My husband seems to be set on Cambria white! But that might be more due to him being tired of ldiscussions about the countertop.)

Might be best to bring your countertop samples home to see how they look in your space with your lighting and cabinet colors. Maybe it's my monitor but the Iverness Frost looks more creamy white vs the Misterio. I wouldn't even look at backsplash tiles until after the cabinets/counters are installed, might be too many competing whites but with right combination can be done. The backsplash would need to marry both cabinet and counter to strike a balance. Hope some pros chime in on this for ideas to consider but will likely want photos of your space to see what you're working with.
