I suggest going to a paint shop and bringing home a bunch of chips and/or samples. There are a lot of blues out there, and it will depend a lot on the lighting in the room and other such things we cannot know...

This may be too blue, but it's so gorgeous so I thought I'd share.

LOVE naval. looking for more muted pretty blue with gray. thanks!

I'll keep an eye out! Nothing comes to mind but I do know the perfect color is out there. Maybe stick with one brand of paint and then google search from there. I'm sure you'll find tons of inspiration photos on Houzz and beyond.

Good luck!

yes, i'm only going with Ben Moore; otherwise too many choices! ty.
