Light Blue Walls Curtain What Colour Of Paint Should I Choose For My Walls And Trim In A Room With Blue Carpet?

What colour of paint should I choose for my walls and trim in a room with blue carpet? - light blue walls curtain

I moved into a new room with tons of space to be creative, but the colors are not as forgiving. Well, there is a dark blue carpet, white walls and blue square. I have already bought a sofa in brown, blue and gold, but I'm not sure what to use the nuances and shades of brown for everything (base, walls, bedding and curtains around). Please help me!
