Does the black flower wallpaper in the bedroom background wall affect Feng Shui?

There is a feng shui letter, and there is nothing wrong with not believing it. If you believe in Feng Shui, just refer to it. It is not advisable to use wallpaper with black tone or too deep color, because such wallpaper looks heavy and depressing, which makes people feel depressed, pessimistic and lacking in vitality, and may also make you sleep badly every night, which is inseparable from the tragic situation of insomnia every day.
