Can you read it? The traditional Japanese color "Mushi Ao" is not pronounced "Chusei"










What is the traditional Japanese color "Mushi-ao"?




Mushi-ao refers to a dark bluish-green color, like the wings of a jewel beetle. The wings of the Yamato jewel beetle, found in Japan, the southern part of the Korean Peninsula, and Taiwan, have reddish-purple vertical stripes on a green background, and have a beautiful metallic luster, so they have been used in decoration since ancient times. A prime example is the Tamamushi Zushi (Tamamushi Shrine) at Horyuji Temple in Nara. This palace-style shrine, built during the Asuka period, has jewel beetle wings embedded under gilt bronze openwork ornaments, which give off a beautiful glow depending on the light. The colors used for the covering were blue-black on the front and indigo or light blue on the back.





Insect blue = Mushiao

 

The wings of the Japanese jewel beetle shine not with pigment but with structural color due to their light-reflecting structure. As a result, they are known to retain their metallic luster even after death without fading. "Mushiao" is pronounced "mushiao."
