≪ Design ≫

"Nakamura"
This pattern is called “Nakamura Gōshi.”
Patterns that used writing in this way were popular in the world of Kabuki during the Edo period, around 1800 CE. As a normal pattern would be dull, Kabuki actors thought of designs that contained puns on their own stage names and made yukata out of them. They are appealing designs that are still in use today. Not just the“Nakamura Gōshi,” but also designs like the “Kamawanu”.
This design was the pattern used by Kanzaburō Nakamura, and uses the Japanese characters for “naka” (中) and “ra” (ら). The place where the six lines are used represents the character for “mu” (六), as the number of lines in the pattern is similar to the character.
This spot where the “naka” and “ra” characters are not facing the same direction is considered an aspect of the design.

≪ Color ≫

Deep Pale Blue (Hanada-iro)
Originally, this term referred to a color made using the liquid of pressed dayflower petals as a dyeing agent, but this blue faded extremely easily and would disappear on contact with water, so it was commonly used to indicate a color made with the far more durable indigo plant, and appears to have been used long ago as a general name for colors in the common blue family. However, the commelina communis var. hortensis, a cultivated variety of the tsuyukusa (Asiatic dayflower), is still used in textile design crafts like Yuzen dyeing.
