I think your colors are restful so I would work with those and not pop a color. Maybe some interesting artwork that had some color in it, but I think you should go for a more elegant calm look. By the way, I like the chandelier you have with the fireplace. I think I would paint the lower part of your wall the same blue as is in the top part. Then I would add some black accents in glass and lamps. Curtains that have a sheen or gold thread would be nice.

Thanks jacksplash, was going dark but I have floorboards painted the same colour as the stairs is currently, on the landing too and these would then have to be dark also. Worried in case that would make the whole space too dark. Today I was considering a colour darker than the marble on the wall but somewhere on that tone, which could work better upstairs. Questions, questions??? It's the last place to be painted since the renovations but painters leaving next week so I need to get a move on

It feels bland because floors and walls are beige. (ish). If you want to make a statement about a room. contrasting shades work really well. You have spotlights so the south aspect is irrelevant. Put a dimmer on spots if not already there so you control the light and feel of a room. I presume the fire is staying there so that back wall would be perfect for TV to be put on/entertainment system. Corner couch facing tv wall with chaise lounge on fire side. Behind the corner or L shaped couch, table and chairs so the room is functional for entertaining also and the layout is proportional. The room also has a focal point (TV)

You can really afford to go for drama in a bedroom and paint it a dark color if you like. If you find that a bit of a 'commitment' I'd go with a dark wall where your headboard should be. It would work well with the frames and mounts that are on your pictures above the bed. I can see you're currently sharing your room with a baby so a blanket box (a decent one you can sit on) would be a good investment to get those toys out of view. Don't go crazy with wood, I'd get one you could paint and change the up the upholstery on the lid so that you can update it every 5-7 years as you will with your room.
