Dark Pine Green
It must be a favorite color of mine, as I now have two full bottles. I will also have to learn to read Japanese Kanji Script to avoid duplicating inks again (which I have written down for reference) . Great dark green forest come to mind.
"Seaweed is a very accurate description for this ink -- fresh, green-blue seaweed. It's a color with lots of depth and it shows different attributes depending on the wetness of the pen and the quality of the paper. It has become the ink I use in my best pen, since it has a dignity about it that seems to call for a good instrument.
