Caihua
Caihua (Chinese: 彩畫; pinyin: cǎihuà), or "colour painting", is the traditional Chinese decorative painting or polychrome used for architecture and one of the most notable and important features of historical Chinese architecture. It held a significant artistic and practical role within the development of East-Asian architecture, as Caihua served not only decoration but also protection of the predominantly wooden architecture from various seasonal elements and hid the imperfections of the wood itself.
