High-fidelity imaging is a key technique for digital protection of Dunhuang murals. Based on previous studies, we developed color charts and studied color management of digital imaging for Dunhuang murals. In terms of visual effects, our results show that the Dunhuang mural color charts we developed are superior to the standard Macbeth ColorChecker color charts based on subjective comparative evaluation under the same photo-shooting conditions. In addition, other results also show that the Dunhuang mural color charts can function well in color calibration under different illumination or color-bias conditions.
