The color is true to the color on my screen, and it flows excellently from my Pilot Decimo.

Wow. Amazing color, great bottle design, and pretty much fantastic everything else. More of a blue-black ink, the tinge of green in it makes for a unique color and change among more traditional blue-blacks. This is a great color to use in the workplace as well as just for fun. It's super smooth and the color is vivid and intense like the rest of the Iroshizuku line, and definitely shouldn't be missed.

This is almost a blue-black but with too much green to be a true blue-black (I think). It's a fun color and just as saturated and lubricated as the other Iroshizuku ink I've tried. Probably one of the few that actually looks like the color on the box.

Next to Sailor's excellent blue-black, and Noodler's deep, deep dark and, nearly, permanent, blue-black, Pilot's Tsuki-yo Iroshizuku (Colors of Nature) ink is certainly one of the best blue-black inks that are currently available.
Tsuki-yo, literally Moon-like ("tsuki" means moon), is "Moonlit night," a more appropriate translation (a beautiful Japanese idiom). The ink has a lovely intensity and richness that makes many other blue-black inks look watery and weak.
Currently, Pilot manufactures a pretty, well-made fountain pen to match this color. It is a Custom Heritage 91 model to match Iroshizuku Tsuki-yo. The pen retails for 10,500 Yen in Japan which is about U.S. $115.00. I have one and it writes very well with its 14K rhodium-plated nib. I recommend that JetPens market this model and the other Iroshizuku Custom Heritage 91 pens in Yama-budo, Yama-guri and Kiri-same (models available as of Feb. 2010). More colors will be coming out with barrels and caps made of plastic resin that match the various ink colors, and clips & trim are rhodiumplated steel. They are wonderful writing instruments to go along with some of the most beautiful inks ever produced.
