While the venerable Kōjien dictionary only had black-and-white illustrations, the three competitors took advantage of color printing technology. For instance, all included appendices showing Japanese color names and corresponding colors. First, the Nihongo Daijiten (1989) appendix printed 350 colors and names (色名辞典 "Dictionary of color names", with notes and page cross-references). Second, the Daijisen (1995) appendix had 358 (カラーチャート色名 "Color chart of color names"). The 1st edition Daijirin (1988) was printed in two colors, and the 2nd edition (1995) added a color appendix displaying 168 (色の名 "Names of colors", some with Classical Japanese quotations).
