I have a dinning room with the attached color, a you can see the wood color is light and pale, the walls of the dinning room are painted in light beige color (light cafe au lait). I was thinking of making the wall in the background of the dinning table and the buffet as an accent color wall. I was wondering which way should i go for: wallpaper, slates/ stones/ wood, or just use a different paint color for the wall? and which color should i go for? putting in mind that the floor is light beige marble and the chairs have light neutral colored fabrics.
