Sounds like your daughter's already got some interior designer instincts ;) Loving the black feature wall, and you don't want to take anything away from such a strong statement, so I think you should go with white... or at least a very light grey, e.g. Dulux Lexicon quarter (on the left)...

Hi Sandra, what a beautiful room you can make, I would love your fire place, my thoughts would be to go the lighter colours including painting you panelling, as a few others above have suggested keep the trim and wall colour similar, big floor rug as suggested also. Our sitting room is 4x4 metres, when we first moved in, I painted it quite a dark pink shade and had way too much dark furniture from our downsize that I thought I could not live without. After two years of trying to make myself like it, I finally heavily culled furniture and changed paint colour to a very light grey tone. It probably isn't my perfect colour choice but heaps better, I also purchased some lighter profile furniture, I sit in this room so often now, I just love it, it has gone from a room I tried not to look at, to a room I really like being in. I will put a couple of before and after in for looking at darker colours to lighter colours from very similar angles

I would choose a grey sofa, but really any colour would look great, tan leather, white , depends what style you are looking for, could be ultra glamorous or a casual boho luxe , love those colours throughout, could look gorgeous

Love it, it has so much light it really pulls it off. My sister has a black den, which is such a diff mood to the rest of her house it has a great mood at night, but it lacks the natural light for day time use unless you feel like brooding over a brandy
