I am with the few that don't like them to be painted. I've seen too many that were sloppily done, and/or obviously had many coats of paint applied over the years. Painted ones tend to be more difficult to dust, because the paint used is usually the eggshell or flat wall paint, not glossy in the same color as the wall. However, since yours are already painted, I would say keep, or paint, them the color of the wall and not change them to white. Painting them white now serves no purpose.

A brown sofa and golden orange wood cabinets are complimented by browned down greens and grayed blues. Find a rug with a lot of the below colors, and do the SW Sawdust for most of the walls. The blue and copper work for pillows, drapes, and maybe even some accent furniture.

BM Simply White ceiling and BM ballet white for walls. Looking at it from other side, I’m again thinking ceiling color, so as not to highlight the post that we unfortunately can’t remove.

Hi sorry no one has answered yet, did you go through with anything yet? I think it’s not easy giving advice on white without being there in person. However, there can be some clues like lighting conditions / direction of window facing, uou said you are using terracotta, so you can find something with an orange, red or yellow undertone in it and avoid anything with blue or green… unless you want it to stick out. I think you getting samples is a great idea. I found light colors arent easy because it can have indertones that you might or might not expect to show up & can look dofferent from room to room. Shoji white I think has green undertones, but depending on the light snd surroundings, it can look different. you can see how you like it and maybe play with some color cards on the fsn deck first and look at the darker version on each to see what undertones are at play, but thats just the start. Do update when your finished!
