For color reproduction of an facial prosthesis, internal or external color is selected. The internal color is superior with regard to depth, permeability, and stability; however, it is difficult to reproduce. Colorimetric analysis of silicone facial prosthesis materials （KRS-10-2 and KRS-10F-2; GC） using newly developed colorants （CA-R, CA-Y, CA-B, CA- P1, CA-P2, CA-B1, and CA-B2） was performed using samples of varying thickness. There was little colorimetric difference between KRS-10-2 and KRS-10F-2 when silicones were over 5mm thick. Although the color differences among mixed-colored materials varied little regardless of thickness, single-colored materials exhibited significant differences with regard to silicone thickness, particularly CA-Y. Further, few changes in color differences were detected in each sample 1 year after the initial measurement.
