A study on human´s sensibility to agricultural machinery´s color Base on SD Scale

Base on SD scales, the research try to find out human´s sensibility to large-scale agricultural machinery´s color. By dealing with data from the scales by factor analysis method, the study extracts two principal components of human´s sensibility to agricultural machinery. Then by serving the two components as X&Y axis, an image scale of agricultural machinery´ color is made, which can shows some laws of human´s sensibility to agricultural machinery´s color. Finally, by a contrast test, the paper attempts to find whether environment will influence human´s sensibilities to agricultural machinery´s color.
