This is an ink that I can't quite figure out. When I wrote the review, I was thinking it was a straight-up blue/black. As I look at it now, though, it's definitely got a lot of green in it. You can see this in the swatch at the bottom of the written bit. Aw, heck. I'll just post it right here.
Ebony Blue is a dark ink, whether it's really a green or really a blue. The Lamy fine nib that I was using it in is a little on the dry side, so you see more of the green than you would if you had a wet nib. I'd recommend a wet nib for this ink. It's a little thick (as PR inks tend to be) and it's a liable to get a bit dry in your feed if you don't use your pen for a while.

Here's the water-drop test video. It's a little shorter than the others have been recently. My wife came home with a bunch of Girl Scout cookies and the cat was prowling around trying to jump on my desk the whole time. He actually wrecked two video-attempts with his jumping today. Dude just doesn't want to stay on the floor today.
This one isn't all that water-resistant, but it will leave some ink on the page. Looking at it now, it left a lot of green on the page where the water was.
