In order to have proper environmental conditions for housing relics in the museums, the variation regularity of environment factors and its influence on the relics should be well understood. In this study, the environmental temperature and humidity of the exhibition and storage rooms of the Palace Museum were monitored. Besides, the color variation of four kinds of silk goods and painting papers with different colors exhibited or storied in these environments were also measured. The 5-year experimental data analyzed show that the changing degree of the sample color depends on the nature of the materials. Among the silk goods in the same conservation condition, the red one is the most sensitive to the environment. On the other hand, the pigments of the painting are less affected by different environmental temperature and humidity.
