Abstract
Displays tends to expand its color gamut, such as multi-primary color display, Adobe RGB and so on. It is now possible to design computer graphics using previously unavailable colors. However the environment for contents production is not yet established. In order to using wide color gamut effectively, we have developed contents production systems and prototype graphic software with six primary color display. And we have developed a user interface for mixing the six primary colors easily. Through creating wide color gamut contents with systems that we developed, we confirmed the effectiveness of our systems and contents. In addition, we have researched the psychological effects of viewing an extended range of colors.
