I LOVE THIS RUG!  This was my third rug purchase trying to find the right color of blue for a guest bedroom.  As you know, describing the color blue is tricky and it never seems to work out!  I would say this is more of a spa blue, but there is probably more silvery gray tones to it than anything.  I think it looks a bit more blue in the room I am using it for due to having bedding that I would call Spa on it.  It's really beautiful and looks very high-end and expensive.  The rug is also very soft to walk on.  Love it!
