It's just a base color of blue...and then a clear glaze for the stripes. They show up a lot better on the picture than in the room because of the flash. I like them because they are subtle. I did this in my half bath too on a deep brown, and it looks great!
If you do 2 different colors, there's a technique so that you don't get any color seeping through the tape - that would look awful with stripes! The glaze is a little easier because it doesn't seep as much, and if it does you have 45 minutes to wipe it off - so I pull the tape pretty quickly after I'm done.
