It depends on the orientation and location of your home and the attributes of your home. For example, the background wall in the east is made of wood, which is not good for Jin people. If it is not good for Jin people, use water to achieve balance. The color is mainly elegant, and white, lavender and light blue can be used.
If the background wall is in the west and the west is gold, it is Jin Kemu, which is not conducive to people with wood attributes, so bright colors are more suitable for the background wall. Red, orange and yellow will do.
