The living room is located in the west, facing the north background wall to get what color

As for what you said about being located in the West, most of them are centered on houses, not on the coordinates of the earth. So don't think about it from the perspective of Feng Shui, there will be a lot of unscientific thinking in that way. From the perspective of contemporary design principles, what color is used for the background wall can be considered from three aspects: indoor lighting, design style and environmental atmosphere.

For example, when the light is dark, you can use white, blue, white, light yellow, etc., from the atmosphere of the environment, such as using a cool color in summer, such as white, blue, etc., you can feel cool, and in winter, you can use a warm color, such as yellow, red, etc., to bring warmth. Of course, it can also be considered from the perspective of personality, and it can be based on personal preferences.

If the living room faces west. Then the sun will shine a lot.

Therefore, if you want to decorate the wall, use cool colors as the main thing.

Personally, I feel that the west-facing is also not bad. There is sun in the winter, but it is a little warmer in the summer. But now in the summer, it's nothing to install curtains and air conditioning in the room

According to Feng Shui. If you face west, it is easy to make people irritable, and the internal fire is hot and dry. So. So I don't know either, by the way = =!

Paint beige facing west for added brightness.
