What is "Miru-iro" (seaweed green)? Origin and etymology.

The name "miru-iro" (seaweed green) originates from "miru," a type of green algae that grows on rocky reefs in shallow seas. This seaweed has been used for food and medicine since ancient times. Its deep, slightly muted yellowish-green color is considered the direct origin of the color name. Miru gets its name from its resemblance to pine needles, and its hue has become established as one of the colors that symbolize the Japanese view of nature.

The word "umimatsu" (seaweed) was used in waka poetry as a pun on the homophone "miru" (to see), expressing a wish to meet a loved one. It was also associated with "miru," meaning to rule or govern, and was therefore considered an auspicious word. These wordplays and auspicious connotations contributed to the fact that the color "umimatsu" (seaweed) became more than just a color description; it became a color with a cultural background that people cherished.

The historical background of the seaweed color

The history of the seaweed green color is long, dating back to the Heian period. The section on the Imperial Sewing Bureau in the Engishiki (a compilation of laws and regulations from the Heian period) describes the dyes and methods for dyeing seaweed green, indicating that it was recognized as an official color even then. Heian aristocrats favored this color, and the combination of "seaweed green" and "miru" (海松) even existed in the "layered color combinations" of clothing.

During the Kamakura period, its subdued hue and auspicious connotations made it popular among the samurai class. In particular, it is said that this color was sometimes used in armor and clothing as a good luck charm to pray for victory in battle. In the Edo period, it became popular among commoners as well, and was widely used in kimonos, obi sashes, and accessories.

Related literature, waka poetry, and seasonal words

The color "miru-iro" (seaweed green) can also be found in classical literature. A prime example is the "Matsukaze" chapter of "The Tale of Genji." Among the garments that Lady Akashi gives to Hikaru Genji is a fabric of "miru-iro," which is effectively used as a color symbolizing the seaside scenery and the emotions of the characters.

In the world of Japanese poetry, "umizu" (seaweed) frequently appears as a pun on "miru" (to see), and was used to express feelings of love or longing for reunion. For example, the poem "Wabinureba ima wa ta onaji Naniwa naru mi o tsukushite mo awamu to zo omou" (I am weary now, but I will risk my life in Naniwa) also refers to the sea of Naniwa where umizu can be found. Furthermore, umizu itself is sometimes used as a summer seasonal word in haiku.

FAQ

❓ There is a color similar to "seaweed green" called "pine needle green," but what is the difference?
Miru-iro (seaweed green) is a dark, slightly yellowish green, derived from the seaweed "miru." On the other hand, Matsuba-iro (pine needle green) is derived from the color of pine needles and is a deeper green with a stronger blue tint than Miru-iro. Both are traditional green colors, but they differ in their origins and shades.
❓ The color seaweed green is considered an auspicious color, but why?
The word "miru" (海松) is a homophone for "miru" (見る), meaning to see someone you long for, and "miru" (御る), meaning to govern or control something. Therefore, it was considered auspicious as a pun. In particular, it is said that among samurai, it was used on weapons and armor as an auspicious color to pray for victory.
❓ What season does the color seaweed green remind you of?
Because seaweed green is a deep, calming green, it is mainly used to express the feeling of the season from autumn to winter. This is because it goes well with colors that represent autumn, such as withered leaf green and persimmon color. However, seaweed itself is a seasonal word for summer, and depending on the colors it is combined with, it can also be a universal color that can be used throughout the year.
