This wall color is fantastic and is a great example to show that when you don't have much wall showing, you can go with a vibrant color that makes your heart sing every time you walk into the space. While we wait for the designer to tell us the exact shade, look at something like Ben Moore's Maritime Blue/667.

I have Behr's Southern Breeze on my kitchen walls and after seeing BM's Maritime Blue, it does look very close. I did my upper cabinets white and looking to do maybe a Sapele counter top on my island, so now I know the color scheme will look refreshing :)
