Blue or Green?

My mom and I took a trip to Benjamin Moore yesterday to pick out/up the paint for my condo. My bedroom is definitely going to be painted the same blue as it was in my parents' house and the living room/kitchen area was going to be blue as well but a few shades lighter. When we got to the store my mom was being a tool and refused to pick a colour (she hasn't had a problem picking out every other thing for the condo!!) Anyways, I gave the woman at the store a sample of the blue from my bedroom, the colour of my new couch and showed her a couple pictures (so she could see the different colour woods). We started in the blues but made our way to golds and then to greens. Since blue was always assumed, there are a few things that won't go with the green (nothing major) but now I'm really set on the green! What to do, what to do?!
