I agree with the other comments, wait until you white wash, but I would be tempted to paint some colour of the walls if you cannot remove the trim (it might be there to tidy up the joins).

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

Dear Creatively Challenged , I can recommend Dulux Colour Consultants, I gave up after about 5 sample pots . At the time it cost me $150 and if I used dulux paints I could claim a full refund . That was 12 years ago . I didn’t realise at the time just how good they were , the colours are still in fashion but it’s ready for another paint job for sure. It was such a relief to have someone in who is trained and fully understands colours and fashion and what goes with what . I finally stopped stressing about it and got the job done ✅

Hi Sue, I think the wall colour (white looks like an white/off white) is lovely. It’s neutral and light, and will be the best back drop for any soft furnishings. I would suggest maybe updating some of your furniture. Your sofas look in good condition, so re-upholstering to change the colour may be a expensive option. in a bid to save some money, perhaps updating your rug to a lighter/more neutral pattern/colour (look at armadillo rugs) is a better option. Also updating your dining setting (perhaps something with chair upholstery to compliment the sofa, and even a large light coloured marble top) to be more contemporary and in keeping with your lounge suite would be the way to go. My clients often find it difficult to part with certain pieces that hold sentimental value, but often a new home requires a furniture update. In summary, I’m not convinced changing wall colour will be able to link all your furniture together. Stick with one piece that works well (ie. the sofa) and work towards updating the rest. Good luck!
