This paper proposes a method for establishing a scientific pigment color database for the murals of Dunhuang consisting primarily of the following procedures: 1) To build a basic color system for pigments used at Dunhuang and to quantitatively and nondestructively calibrate each color sample of the color system, including spectra, color, particle size, and chemical constitution. 2) Based on the research results of the "Digital Dunhuang" project, to precisely segment and catalogue the image data of already digitized caves, and to nondestructively calibrate each segment so as to obtain the data of each space, including color and physical and chemical properties. 3) To map out the relationship between each segment of the caves and the color samples from the basic color system database, thus connecting the first and second elements of this method to provide a clear picture of the location and color of pigments used in the murals of Dunhuang.
