What is the name of the colored painting on the beams of the Ming and Qing Dynasties?

Color painting is an important part of ancient architectural art in China. Inside and outside the Tiananmen Gate, the three halls of the Forbidden City, the Temple of Heaven, the Summer Palace, the Lama Temple and other important buildings, especially the gold, red and green paintings under the eaves, enhance the color contrast of these sheltered components, and at the same time make a transition between the yellow-green roof and the scarlet pillars below, making the buildings more brilliant and gorgeous. This is indeed a very successful technique. Architectural color painting also has practical and beautification functions. The practical aspect is to protect wood and walls. In ancient times, there was a pepper house, that is, pepper was added to the paint, which not only protected the walls and beams, but also distributed fragrance to repel insects. The function of decoration is to make the inside and outside of the house bright and beautiful. In the early days, colorful paintings were painted on buildings, and various animals, plants and patterns were gradually painted. Later, it was gradually standardized and stylized, and it was not customized until the Ming and Qing Dynasties. Color paintings in the Ming and Qing Dynasties are mainly divided into two categories. One is a completely patterned color painting, which is divided into greetings (with golden dragon and phoenix as the theme), golden dots of gold thread, golden dots of ink thread, golden cut ink, cigarette cut ink, realgar jade, elegant five ink and so on. They are all ranked according to the amount of money used and the main theme of use. The other is "Su-style color painting" (Su refers to Suzhou), which is characterized by drawing a large-scale baggage-like outline on the beam Fang, and drawing various landscapes, figures, flowers, birds, fish and insects, as well as various stories and drama themes on the baggage skin. There are also some ingenious color paintings. For example, the pillars of the Hall of Supreme Harmony in the Forbidden City are decorated with gold powder, and dragons are wrapped around them. The Empress Dowager Cixi Mausoleum in Zunhua Qing Dongling painted golden color paintings on nanmu beams, reaching the peak of resplendence.
