In the first part, the results show two illuminants are better than one, and the best combination are CIE F4 and F11. The proposed model can suppress color errors below 2 �媧00. Using single light source with color filter also can obtain 6 channel color signals and using A illuminant with orange-red color filter give the best results. It would be useful to the development of multi-illuminant cloth color simulation systems. In the second part, an outfit color simulation system was proposed based on Ou's color emotion model and Moon and Spencers' color harmonic model. The software is composed by image segmentation, color selection and color rendering. It first converts the intensity of 10 color terms given by the user into 3 principal components, and then uses the 3 values to find colors having the given semantic image. The second color is selected based on Moon and Spencers' model. The proposed system successfully simulates outfit colors based on certain semantic image with high degree of color harmony.
