The Asian Organic Colorants project is a collaborative scientific research project to develop a strategy for the analysis of traditional Chinese organic colorants used as textile dyes and organic pigments in Chinese wall paintings and for the analysis of organic colorants used as textile dyes and organic pigments in Asia. Detection and identification of traditional Chinese organic colorants presents a challenge not only because many of the biological sources used to create them have not been well studied, but because in the case of is organic paints, concentrations of these colorants are relatively low compared with inorganic pigments and binding media. Much less is known of these colorants than of the dye and organic pigment sources used in Europe and the Americas.
