Another one with pale yellow walls.
I have a basement sewing room with one window that faces NW. I have wood panelling on 2 walls, one day I will replace it with drywall, but not until we rewire the house as the electric box is in that room. The other walls and curtains are a pale buttery yellow. My floors are light grey painted concrete.
The pale yellow makes the room feel bright, even with just the overhead light turned on.
You mentioned coral, that would be nice too as long as it was light and did not interfere with colour perspective.
The sun gives off Yellow light, not white light, so anything we look at outdoors will have a yellow hue. This is why so many of us do not like LED or other pure white light, it is not natural. I do not worry about using pure white light to match colours, because I do not live in a pure white light world.
