What is "mouse gray"? Origin and etymology

As its name suggests, "mouse gray" is a traditional Japanese color derived from the color of a mouse's fur. In the past, it was simply called "gray" or "lead gray," but it is believed that the name "mouse gray" became common around the early Edo period. Although it is an achromatic color, the slight inclusion of blue, red, or yellow hues creates a variety of shades, fostering a culture of appreciating these subtle differences.

This color was widely accepted as a symbol of refined aesthetics, reflecting the samurai spirit of avoiding ostentation and the townspeople's culture that valued simplicity and frugality.

Gray historical background

Gray became particularly fashionable during the mid-Edo period. The shogunate frequently issued sumptuary laws, restricting commoners from wearing silk fabrics, gold and silver threads, and brightly colored clothing such as purple and crimson. As a reaction to this, people began to find enjoyment in subtle variations in shades of muted colors like brown and gray, which were not subject to restrictions, and this was considered "chic" or "stylish."

This trend gave rise to the phrase "48 shades of brown and 100 shades of gray," and many derivative colors such as silver gray, Rikyu gray, and indigo gray were created. These were not merely substitutes under constraints, but rather expressions of the creativity and aesthetic sense of the townspeople of Edo. Colors favored by Kabuki actors also became popular, and gray, linked to culture, became established as one of the important colors symbolizing Edo culture.

Related literature, waka poetry, and seasonal words

The color gray frequently appears in Edo period literature and ukiyo-e prints. In Ihara Saikaku's ukiyo-zoshi, as well as in sharebon and kokkeibon, it is depicted as the color of the characters' clothing and used as a prop to express their social status or refined character. In particular, gray kimonos are often depicted as a color favored by Edo's pleasure-seekers and stylish people.

While gray doesn't have a specific season as a seasonal word, it's sometimes used to express the cloudy skies of winter or a sense of loneliness. In the world of waka and haiku poetry, the color "gray" isn't often used directly, but its quiet and calm atmosphere resonates with the aesthetics of wabi-sabi. Since the modern era, it has been used in many literary works to depict urban, sophisticated, or melancholic scenes.

"Forty-eight browns and one hundred grays" is a phrase that indicates the vast number of shades of brown and gray that existed during the Edo period. "Forty-eight" and "one hundred" are not actual numbers but metaphorical expressions meaning "very many," symbolizing the culture of people at the time who found subtle differences within muted colors and enjoyed a sense of refinement.
❓ Why is gray considered a "stylish" color?
During the Edo period, sumptuary laws prohibited bright colors, so people found beauty in browns and grays, which were exempt from these restrictions.
