Abstract. As an example of color, vision two-color method by Land was introduced. Experimental procedures of this method were done as follows: first, we took two stil-photographies with a red filter (L record) and green filter (S record); second, these nega films were reversed in the posi films; third, these films were projected on the screen by two projectors and the projected -pictures were superposed. In the third step L record was projected with a red filter and S record was projected without filter.
From the experiment mentioned above, we could recognize the full color of stil on the screen though we expected that mixed color of red and white were shown on the screen.
