11 映画館ロビーの全体色調検討のための情意実験

Abstract

The superiority of the color of a movie theater lobby depends on its whole tone of color, especially on the warmth given by the tone. We, through the cautious methodological research, found that the psychometric method is effective in order to treat this problem, and made the following experiment. First, in advance of the experiment, we measured and recorded the colors of the movie theater lobbies in Tokyo, and at the same time we took color photographs of these lobbies. Second, we picked up thrty those photographs as examples. Then, according to the method of paired comparison as a psychometric method, we showed them to four observers (who have excellent aesthetic sense) in order to get their answers about the superiority, warmth, and intensity of stimuli of the colors. We aranged these data statistically, and gave the examination marks to every lobby. Further, we examined the relation between the superiority and the warmth of every lobby and anallised some factors which are thought to be related to the warmth of the lobby, the balance point, illuminant color, illumination, etc. And then we examined the relation and the factors from various viewpoints, using many data connected with this problem. As the result of the avove mentioned research, we got the following conclusion. Most of the successful examples were found among the comparatively warm ones (whose balance point is in most cases in the warm colors more than chroma 4) and the comparatively cool ones (whose balance point is in the achromatic colors less than chroma 1). The main contents of this paper is the full account of the methodological research of the above mentioned experiment.
