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).

Hey Dounia The colour and the way it has been painted is very much what we saw in the late 90's and early 2000's when we all went through the textured paint feature wall craze. But, saying that Paint and design technology have come a long way since then and I would encourage you not to give up on the copper idea and use a modern approach and product. Dulux have recently added their new range of Design Effects, Here's the copper and concrete look. There's also other options available at www.dulux.com.au. You can email them for a copy of their brochure or they are readily available at Bunnings in the paint section. Thanks Paul

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 ✅

Avoid paint as it wears. Stained or oiled timber would look great with a navy door.
