Rohrer & Klingner Fountain Pen Ink (50mL) - Verdura

This is a very pretty mid tone true green. It is less bluish than Smaragdgrun. However, I found it was not dark enough and did not provide enough contrast on paper, so readability was reduced for me. (I am 61.) Beautiful colour though. It flows well and is well behaved.

This ink is an amazing deep green. I currently use this to take notes for school and I am loving it.

It is very smooth however it doesn't have very much water resistance so if you need something to be 100% water proof, this isn't your ink.

There is some minor shading and it acts very nicely however it isn't a huge dramatic ink like Emerald of Chivor or anything.

Basically if you want a nice grassy deep green that isn't too dark, but isn't too light, this is the one.
