Can anyone recommend a cool emerald/shamrock green (i guess thats the best way i can describe it)?

Noodler's Emerald City, very bright green that really pops.

Noodler's Gruene Cactus is nice.

You can try finding some vintage emerald green Skrip- good luck with that one. I got lucky when I found some the first time. Emerald City green by Noodlers is nice, but you have to order it from worldlux.com.

Diamine Emerald or Woodland.

Or, Caran d'Ache Amazon. Comes with a cool bottle you could use for
a cute inkwell on your desk after you run out of the ink and decide to
try a different green.

Caran d'Ache and Diamine are my two favorite ink bottles.

I'm enjoying the Omas Green that I bought for springtime the other day. Really bright, like new-growth leaves.

I think the Diamine Woodland green is a bit dark to be called 'Emerald', unless you are comparing with real jewels - then it's a bit light. The Diamine Emerald green is lighter. If you can get any Green Parker Quink, that's a fairly characterless Emerald. The colour is close to Emerald though.

I should have mentioned Quink Green. I purchased six bottles last year. Very nice green.

I find the new Skrip Green quite nice, but taste is a subjective thing.

Checking Clark and my memory, it is a bit deeper and more subdued than the old Skrip Emerald Green.
