What does black say in Feng Shui?

1. In the Book of Changes, which is called the cultural source of China, black represents the sky and the north where Tiandi lives, and black has become the most important color in the Book of Changes. 2. Each hexagram in the Book of Changes has its own color as a representative. Among them, the hexagram is black because the yang in the middle is surrounded by the yin on both sides and the light is trapped in the darkness.
