Abstract: The color of materials is intrinsically linked to their chemical structures. By exploring the mechanism behind material coloration, we can enhance the public’s perception of chemistry. This article uses traditional Chinese plant dyeing as a focal point to design layered experimental activities, including the extraction of natural pigments, the simulation of the intangible cultural heritage process of Xiangyunsha dyeing, and the colorimetric identification of iron elements. These interactive experiments showcase the beauty, intrigue, and scientific foundation of chemistry, while simultaneously highlighting the allure of traditional culture, fostering the fusion and dissemination of science and heritage.

Key words: Coloration, Traditional Chinese plant dyeing, Coordination compounds, Popularization of science
