Here are those paint color options I promised you earlier. Let me know if you use one or more of them for your walls. Better yet, send a photo! :)
Blue Lagoon - Closest match! - #2054-40
Teal Ocean - A bolder turquoise blue - #2049-30
Blue Spa - A medium marine blue - #2052-40
The above colors are from Benjamin Moore's Color Preview Collection.
Go with Decorators White for a pure white or Navajo White for a slightly warmer white. Both are from Benjamin Moore's Interior Collection.
Find all of these colors using the Benjamin Moore Virtual Fandeck. It's fun!
