In ancient buildings in China, color is very particular, and golden yellow is a sign of the authority of the royal family, which is not allowed to be used by the people. Now we can also find from the palaces, tombs and gardens of emperors that all kinds of buildings related to the royal family are decorated with golden glazed tiles, which is a custom inherited from the Song Dynasty.
In our country, red is considered as a festive color, which means solemnity and wealth. As early as the Zhou Dynasty in 1 1 century BC, red was widely used in palace buildings and spread to later generations. Because the palace of the feudal emperor is the activity place of the supreme ruler, it should be "supreme" and "noble and rich" everywhere, so the walls of folk buildings should not be painted red.
The color of the roof is the most important, and the yellow glazed tile roof is the most distinguished. Except for a few special requirements, all buildings in the palace, regardless of size, are yellow glazed tiles. Below the palace, the temples, palaces and temples are mixed in yellow-green (trimmed), green and cyan-gray; Residential buildings have the lowest grade, and only gray pottery tiles can be used. The walls of temples and main buildings are all red.
Black, generally used for low-level officials and wealthy families, but also for special places. According to the Five Elements, the water in the north is matched with black, and the roof of the Palace Museum uses black glazed tiles, indicating that water is used for fire fighting, and temples are also equipped with black tiles, which represents the low level and shows the idea of being in the middle. The simple distinction is royal yellow tiles, official green tiles and civilian black tiles.
