That is a very nice "mellow" shade of blue. I will definitely look that up at the paint store.

Try Restoration Hardware Atmosphere Blue.

I started with an EK shade of blue but added some white, a touch of black, and some other leftover paint and somehow I ended up with this great color!! I wish I could recreate it one day.

We used Sherwin Wiliams "Krypton" for one of our bathrooms. It's somewhat of a soft blue/gray in color that tied in nicely with our carrara marble tile.

I just saw a pic of a room painted BM Beacon Gray - a really pretty blue color.

My bathroom is Ben Moore Van Cortland Blue. It's a medium-dark grayed blue. I have lots of white to counter it, and a sunny southwest exposure. I also have a black and white print on the wall and I think it looks nice with black and white. I do not have a picture of the room readily available but I can get one for you if you're interested in seeing it.

Here's a picture of RH Atmosphere Blue.

I have BM Adagio in the powder room (no windows/natural light) and it's a great blue with gray undertones. I don't have a good picture of it, I'll try to get one and post later..

Used this grey/blue in my mom's basement apartment in our house. We have white and black subway tile and a grey/black granite floor. She has one window and it looks great. Picture does not due it justice. But friends used the same color in their bathrooms after seeing it.

Here is another photo of RH's atmosphere blue. I have it in my downstairs bathroom and laundry room. It's really neutral.

The paint color in my mom's bathroom is Behr Skipper.
