What is Hanaryokushō? Origin and etymology

Hanaryokushō is the Japanese name for "emerald green," an artificial pigment imported from Germany during the Meiji era. Its main component is copper acetosarsenite, and it is known to be highly toxic. The name is a combination of the prefix "hana," meaning something beautiful or excellent, and "rokushō," which refers to the bluish-green rust that forms on copper.

It is believed to have been named with the meaning of "particularly beautiful verdigris," and was given this name because its vivid color was unlike anything seen in traditional Japanese pigments up to that point.

Historical background of verdigris

In the early Meiji era, new chemical pigments were introduced to Japan from the West, one of which was verdigris. Its vibrant color was unlike anything found in traditional Japanese paints, and it attracted the attention of some artists. However, due to the strong toxicity of its main component, copper acetosate arsenite, its use as a paint gradually declined. On the other hand, its toxicity was utilized to its advantage in a history of being widely used as an insecticide, rodenticide, and paint to prevent barnacles and other organisms from attaching to the hulls of ships.

Nowadays, safe alternative pigments have been developed, so the inherently toxic verdigris is no longer used as a pigment.

Related literature, waka poetry, and seasonal words

Hanarokushō is a relatively new color name that appeared in the Meiji era, so it does not directly appear in classical literature or waka poetry from the Heian or Edo periods. However, its vivid blue-green color is reminiscent of the deep pools and streams of summer, or the leaves of evergreen trees. In modern literary works, as new color sensibilities influenced by Western culture were incorporated, vivid depictions of green reminiscent of Hanarokushō can sometimes be seen.

Although it is not an established seasonal word, its colors strongly evoke a vibrant summer scene.

FAQ

❓ What is the difference between verdigris and verdigris?
Verdigris refers to the bluish-green rust (such as basic copper carbonate) that naturally forms on the surface of copper, and has been used as a pigment since ancient times. On the other hand, hana-ryokushō is an artificial pigment mainly composed of copper acetoarsenite, which was introduced from Germany during the Meiji era, and is characterized by its much brighter color and stronger toxicity than verdigris.
❓ Is verdigris still used today?
The highly toxic pigment verdigris (copper acetose arsenite), once used as a pigment, is now rarely used due to safety concerns. Paints and coatings sold today under the name "verdigris" are alternative pigments that reproduce its color using safe chemicals.
❓ Why does the word "flower" (花) have "green" (花) in its name?
In Japanese, the word "hana" (花) is sometimes used as a prefix to refer to something beautiful or excellent (e.g., flower shape, bride). It is believed that the "hana" in "hana-ryokushō" (花緑青) was chosen to convey the meaning that it is a remarkably beautiful and vivid verdigris blue, far superior to conventional verdigris blues.
