Definition: Hongyu refers to an ancient Chinese painting style that developed during the Song Dynasty (960-1279 AD). It was created on a large scale by artists who were commissioned to create religious or mythological paintings. The term 'Hongyu' is derived from the Chinese word for "butterfly" ('huΗyΓΊ'), which means that the painting has a decorative pattern, usually consisting of many smaller squares arranged in a round shape and colored with bright colors. The artistic style of Hongyu involves the use of a flat surface called the "wΓ‘ng" or "wall," which is typically covered in silk. The composition of the wall is carefully designed to create an illusion of depth and complexity, often requiring multiple layers of paint to achieve the desired effect. The color palette is also highly decorative and often includes elements such as reds, oranges, yellows, greens, blues, and pinks. In addition to its decorative qualities, Hongyu paintings are also known for their religious or mythological content. They often feature gods, goddesses, or other figures representing various aspects of Chinese mythology, including the natural world, nature spirits, and the human condition. The style is characterized by a sense of whimsy and playfulness that reflects the playful spirit of Chinese painting tradition. Hongyu paintings were widely displayed in official and religious buildings during the Song Dynasty, and they continue to be popular among collectors and art enthusiasts today.
