In our study, in order to determine a more accurate method for measuring the color of ancient textile relics, we used a specialized color measuring instrument to extract color data from the images of fabrics using image-capturing technology, and then checked and verified the data through auxiliary color cards. L*a*b*, RGB and CMYK data are then exported and recorded in the form of text and images. This procedure can 1) help record color information on ancient textile relics in a more scientific way and standardize digital management of data in a way that will aid further research; 2) provide accurate digitized records for replication or imitation of ancient textile relics, which is conducive to cultural communication and 3) provide accurate data for printing and media promotion of traditional textiles so as to reveal actual colors. We hope this way of recording colors will contribute to the protection and display of ancient textile relics, and other innovative applications.
