We've only been debating paint colours for about 6 months 
We weren't able to have work done on our living room until recently which postponed the decorating.
Anyway..... we knew we wanted an interesting blue on the walls and thought we'd order the curtains to help guide us towards choosing. The curtains are a deep blue/green called sea green. We couldn't get a sample of fabric to take home, even thought they twice said they'd ordered it for us. We went back to look at the fabric and in daytime light, it looks more greeney than blue. So, it's forced us more towards greeny blue paints but I don't want it to look too green and I don't want it to look too cold or a bedroom-like blue.
I think we've narrowed it down to F&B Dix Blue or Light Blue. Does anyone have experience of these colours in a living room or north facing room (wth a big window and still plenty of natural light)? I want the room to feel airey by day and cosy by night. Is that possible?
