Wall colour with this sofa?

[Paddingtonthebear]

Just bought this teal sofa and need to redecorate. It’s a small north facing living room so no direct sunlight but does have a large bay window and some light from an adjoining dining room, oak coloured floors and door.

I'm a complete maximalist but that sofa and this wallpaper mural would be my dream www.grahambrown.com/uk/serendipity-rainbow-bespoke-mural-/120406-master.html

Then some complementary green for other walls.

Forgot to mention, there is a rail around the room

Looked it up and wow, that's a lovely colour

it needs to be a warm based colour as it's a north facing room with cool light, so cool colours like Ammonite will not work. They'll make the room look stark and chilly.

Gold accent wall ?
