The project is a banquet restaurant. Hence, it needs to possess strong artistic features and romantic temperament. The designer adopts the technique of Chinese ink painting in Song Dynasty and color matching skills to build an illusory land of great void with mountains, sea, clouds, moonlight and flowers. The designer used azure as the main color, adjusted the brightness, saturation and contrast, and added black and white to complete the color matching of the whole space, creating a space that is ethereal, clean and rich in the aesthetic features of the Song Dynasty in China.
