I love all shades of blue and I'm trying to figure out the right one to paint my living room.
I would suggest a bright baby blue or maybe a royal blue.
I like soft beachy colors the best so nothing too stark. Azure is a shade of blue that is kind of like the shy on a clear day. I would love something like that but more subdued.
Those sound like good options. I like sky blue and ocean blue. Aquamarine.
Ohhhh, I do love ocean blues too! Aquamarine is beautiful. I could mix that with ultramarine which has some violet in it. 
Ooooh! That sounds so pretty!
I think I'll do that!  Yeah, ultramarine is a darker blue and they grind lapis lazuli into a powder to add the violet tone. I would just have to soften it up.
