There is more to choosing (or not) an accent wall. What is it about the wall which distinguishes it from the other three? Where is it located in the room? Dark colors recede; light colors advance. What is will be on the wall or in front of it? How is the lighting in the room?

I saw a shower where one entire wall was the fancy patterned tile and the other 3 walls were plain. I think it was posted by Beth H? Maybe she will post that again. It wasn't a strip, it was one of the end walls (skinnier) of a shower.

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!

Nice. any chance of updating that ceiling fan? for one, the blades are too short to any actual cooling, And, it's too high. You need another down rod. The style really detracts from the room. Plenty of better looking white ones. a 60" or 62" blade would prob be better. don't know if you would like one w/a light, so here's an option. and these come w/remotes https://www.wayfair.com/lighting/pdp/wade-logan-futrell-62-ceiling-fan-with-led-light-and-remote-included-w006057631.html
