The present color transducer having the wave length spectrum of human color sense, is equipped with the interference filter. But, the interference filter is very high cost, so that the present color transducer can not use many usual color informations. The parpose of this research find the coloring mater to make the low cost transducer using a-Si photo diod. For this parpose, the film having the gelatin layer, was dyed by many coloring maters. These many color filters was measured the spectrum of visible light. As the result, the suitable coloring maters was found, and the spectrum of the transducer is match the same as the spectrum of human color sense. But, at the present time, these filters have the problem of the lasting quality. Furthermore, we intend to experiment with many coloring maters. And a plan of the walking stick having the color transducer to sense a yellow ground mark for the sightless handicapped persons, is proposed in this paper.
