Outline of Final Research Achievements

Color universal design is a color design method for visual materials so that people with color vision characteristics who cannot distinguish some colors, called "color deficiency," can also receive information defined by colors. In this research, we developed a new concept of color universal design method based on the color appearance of dichromats from the starting point of conventional color design work, which is based on the assumption of normal color vision. In addition, as the first step of social implementation, we created a guide map for the Ito Campus of Kyushu University using this method, which was selected for the 2020 Japan Sign Design Award and won the Kyushu Regional Award.

Academic Significance and Societal Importance of the Research Achievements

色覚の特性には、多様性があり，多数派とは異なる色の見え方をする少数派の色覚の特性もあることが知られている．この特性は「色覚異常」や２色覚と呼ばれ，カラーユニバーサルデザインでは配慮の対象でしかなく，色覚の多様性理解までに至ってない．本研究では，色彩デザインを２色覚の色の見えから考案するという新しい方法の実用化をアプリケーション開発を通して行った．今後，社会に本アプリケーションを普及させることができれば，色覚の多様性に関する社会の理解がより深まると考えられる．
