Abstract: In this experiment the shifts of induced colors in a white test fieldwere measured on background of different colored lights by using haplos-copic methed.The color shifts were measured and shown on the CIE 1931color diagram. The results indicated that on the different inducing background of red,green, blue and yellow,a white light roughly appeared to have a hue com-plementary to those lights respectivly. There were some deviations of in-duced color from directions of complementary colors These results mayprovi de clues to further the understanding of the visual process.
