I have never been a green person, but I have recently been warming up to some greens. Basically, I'm starting to like some non-standard greens. This ink review was done with a Pelikan m215 with Binder Italifine nib, which has a 0.9mm cursive italic on the front side and fine round tip on the backside of the nib. It is a pretty wet writer, so YMMV (your mileage may vary) when using this ink in fountain pens with varying flows. I used two papers for this green. The white paper used is 90g Clairefontaine in the small Unplugged Staplebound Duo, which is excellent. The off-white paper is G Lalo.
You can see below how the ink looks on a wider nib (0.9mm cursive italic) and a narrower nib (fine round tip).
I have found the drying time for the ink to be very good in most cases. That said, a wet writer on high-quality paper is probably going to take a good bit longer as the image below shows. Yet, the fine tip dried very quickly even on both papers.
As far as water resistance is concerned, it's not really suited to withstand water. I didn't do a soak test, but I did drop a few drops of water on the page and wipe it off with a napkin, which is probably what I would do if I got water on my notebook while writing at a cafe. For those instances, the ink seemed to fare decently. At least I can still read the text. Note that the ink was fully dried before applying the water.
Diamine Umber is available in 2ml samples and 80ml bottles from GouletPens.com.
