In this paper we performed a set of tests for sound-color synesthete and we were surprised at how consistently the test subjects associated colors with respective to the keys. We compared these representative colors in an animated American film and also discuss how synesthetic colors associated with musical key are adopted in recent Japanese animations. We could see how these colors create special effects and strongly enhances the emotional power.
