Non-destructive techniques were used for colorimetric measurement of silk textiles dyed using traditional techniques. Features of traditional dyed textiles were quantitatively analyzed using RGB, XYZ , Lab and LCh color space parameters. The coloring paramets of the dyed textiles were analyzed by looking at the distribution range and pattern. The effect of dyeing technique on these parameters was also analyzed. The R-G and X-Y parameters have a linear correlation, while C-L parameters have an approximate linear correlation. The distribution of a-b and L- h parameters is within a certain range. Multiple dyeings decreased RGB and L values. Overdyeing had a color additive effect. The colorimetric result of mordant dyeing was mainly affected by dyeing material, not by the textiles. A simple dyeing model is established using the concept of factor of brightness and factor of color saturation to explain the approximately linear relationship between C-L, and the phenomena of decreasing of L with increasing of dyeing time. These results will especially benefit future research on color reproduction and color matching in the conservation of silk textiles.
