A stereo one-shot six-band image-capturing system that combines multiband and stereo imaging techniques has been developed. This system can acquire both spectral color information and depth information at the same time. It worked well for two-dimensional objects that have a wavy structure like a tapestry. In this paper, we discuss the accuracy of color reproduced by using this system. In the experiments, several stereo-pair images were captured while the distance between the two cameras was changed. The estimated color and spectral reflectance of a color chart are compared with the measurement results obtained with a spectrometer and estimation results obtained with the two-shot six-band camera system. It is confirmed the average color difference for 24 color patches of a color chart between measurement data and estimation result is dEa*b* = 1.21 at maximum. Finally, demonstrations of image-capturing of three-dimensional object, image transformation, and color reproduction are presented.
