While my favourite colour of ink is blue, hands-down, I also like certain green inks. Specifically, I tend toward the blue-green (or green-blue, if you prefer) and darker shades,e.g., evergreen. For the most part, my preferred green ink has been Conway Stewart CS Green aka Signature Green (why Conway Stewart named their two green inks – Conway Stewart Green (an emerald green colour) and Conway Stewart CS Green (the darker shade that I prefer) is beyond me; I don’t know how many times I have ordered the latter and received the former!).
A few other (relatively new, I think) green inks have attracted my attention – Pilot Iroshizuku “syo-ro” and De Atramentis “Petrol”. Both of these inks are difficult to source – the Pilot Iroshizuku line of inks can only be purchased through Japanese suppliers, e.g., eBay sellers such as engeika or ujuku123, while the De Atramentis (DA) inks are even more difficult to find. They can be purchased directly from Germany or if you are lucky, you might be able to find a local supplier. Because I am in Canada, I buy my DA ink from Laywine’s in Toronto. FYI, I know that Laywine’s just received a large order of DA ink, so if you want some, now would be a good time to call or email them.
I have inserted a scan of these three inks below – the paper used for this purpose is Behance Dot Grid book paper which is an 80 lb. premium blend. To me, the syo-ro appears to have a bit more blue while the CS green is certainly the deepest green. I am quite fascinated by the Petrol; in hindsight, I wish I would have added some Rohrer & Klingner Verdigris ink for comparison purposes.
All of the inks performed very nicely – nice flow and quick to dry. The CS Green was the only ink to bleed through and most of the writing with it could be detected on the other side of the page.
