PROBLEM TO BE SOLVED: To rapidly and efficiently select a color filter which realizes the transmission color wanted by a customer.;SOLUTION: A transmission and reception part 7 receives signals of the spectral distribution data S(λ) of the light source and the information (xω, yω), Yω of the requested transmission color. An arithmetic processing 21 calculates the information (x, y), Y of the predicted transmission color for the transmission color of each color filter 14 from the transmittance T(λ) for each kind of color filter preliminarily stored in the memory 31 of transmission data and from the received spectral distribution data S(λ). A searching part 22 checks the calculated information (x, y), Y of the predicted transmission color and the information (xω, yω), Yω of the requested transmission color to determine a color filter 14 having the information (x, y), Y of predicted transmission color in the proximity of the information (xω, yω), Yω of the requested transmission color.;COPYRIGHT: (C)2003,JPO
