A prediction method of surface color of union fabric from individual color of yarns and weave was established. Thirteen color yarns were adopted as yarn samples, and sixty union fabrics consisted of two colors of yarns were weaved as fabric samples. Kubelka-Munk's law and Lambert-Beer's law were used to predict surface color as theory of subtractive color mixing. Moreover the isomeric matching method was used for making spectral reflection factor in prediction. It is an ideal color matching method that spectral reflection factor of object color is matched with spectral reflection factor of assignment color. The relationship among the density of predicted color(<I>D<sub>F</sub>(λ)</I>), the density of warp and weft colors(<I>D<sub>warp</sub>(λ), D<sub>weft</sub>(λ)</I>) and the area ratio of warp and weft(<I>S, 1-S</I>) could be expressed as follows:<br><I>D<sub>F</sub>(λ)=S·D<sub>warp</sub>(λ)+(1-S)·D<sub>weft</sub>(λ)</I><br>In order to reduce the difference between the predicted color and the measured color, the difference between density of warp and weft was considered. As a result, the surface color of union fabric can be predicted accurately.
