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.

The iconic summer morning glory has long been a familiar favorite of the Japanese. This shade of blue conjures up the refreshing color of a newly blooming morning glory.
