The name Iroshizuku is a combination of the Japanese words Iro (Coloring), expressing high standards and variation of colors, and Shizuku (Droplet), that embodies the very image of dripping water. Each ink name derives from the expressions of beautiful Japanese natural landscapes and plants, all of which contribute to the depth of each individual hue.

This shade of brown conjures up the image of a ripe, fallen chestnut shell during the longing season of autumn.
