What is "Ao" (blue)? An explanation of the origin, history, and color schemes of this traditional Japanese color.

What does "blue" mean? Origin and etymology

The etymology of the word "ao" is not clearly understood, but the most likely theories suggest it derives from "au" (合), meaning the absence of light, or "ake" (明), meaning the dawn breaking. In ancient Japan, there were few words to strictly distinguish colors, and "ao" referred to a very broad range of colors, including not only the blue we know today, but also green, indigo, and even white and a dark gray. Even today, remnants of this can be seen in expressions such as "ao kosha" (green traffic light) and "ao na shita yama" (a lush, green mountain).

The historical background of blue

In ancient Japan, colors were expressed using four basic words: "aka" (bright), "kuro" (dark), "shiro" (clear), and "ao" (vague). "Ao" referred to a general range of indistinct, intermediate shades. As dyeing technology advanced during the Heian period, color names became more specialized. "Ao" came to primarily refer to colors produced by indigo dyeing, and various shades of blue were created by varying degrees of indigo, such as hanada (light blue) and ai-iro (indigo blue), which were used in the clothing of the nobility.

During the Edo period, indigo dyeing became widespread among ordinary people along with the popularization of cotton. Kimonos, hand towels, and noren curtains were dyed in a vibrant indigo blue, and its durability and the beauty of its color led to it becoming known overseas as "Japan Blue." In this era, blue became a color deeply rooted in the lives of ordinary people, and various shades of blue were enjoyed. Even in modern times, blue continues to be loved by many people as a refreshing color that evokes the sky and the sea.

Related literature, waka poetry, and seasonal words

The Manyoshu anthology contains many poems that use the word "blue," but most of them refer to the green of the mountains. In the famous poem, "Aoniyoshi Nara no miyako wa saku hana no niou ga gotoku ima sakari nari," "aoni" refers to verdigris (greenish-brown) and is used as a poetic epithet for Nara. This indicates that "ao" at that time was a broad concept that included the color green.

In Heian literature, works such as "The Tale of Genji" depict various shades of blue as the colors of the characters' clothing. For example, shades like hanada-iro (light blue) and asagi-iro (light blue) were used as important elements to express social status and the feeling of the season. As a seasonal word, "blue" is often used in words that describe the vibrant nature of early summer, such as "green leaves," "green rice fields," and "green storm."
