A wonderful Olive Green Ink

I've loved green ink for many years. Many years ago I used to add a bit of Pelikan Black to Pelikan Green ink to make a lovely Green/Black I used for all my writing. One day I ended with a bottle of goop when one of the ink formulas changed. I then switched to Diamine Green/Black and used it until it became difficult to obtain. I started using my extra bottles carefully while looking for a substitute. A friend pointed to Sailor Jentle Epinard and I fell in love with it's wonderful dark olive color. (yes, I know it is supposed to be Spinach but it looks more olive to me) . Since Sailor has now discontinued that ink I then switched to Sailor's Tokiwa-Matsu in the Shikiori line of inks which is very close to Epinard. I really like that ink but it's rather expensive. I finally have settled on Diamine Classic Green which is also close to Tokiw-Matsu/Epinard in color, flows beautifully and leaves a nice, high contrast line that is easy to read.
