Diamine Oxblood

Diamine's Oxblood is the darkest of the dark reds that I've been trying. I thought Red Black was the darkest, but this one is way more saturated. In fact, it's so dark that you can only just tell that it's a red at all.

I was using this in my Hero 616 for this ink, and that very fine point doesn't lend itself to shading. There might be some if you're using a much broader nib, but I didn't see it at all. What I saw was saturation so deep it makes the ink look like dried up blood. It's definitely a deep red, but it also has that brownish cast that you get from blood when it dries.

It's a wet ink that will bleed a little on some papers, and it will ghost on most of them. It feathers a little on cheaper papers, as well, but that's to be expected from an ink this wet. 

Check it out next to the last couple of inks that I reviewed. it's clearly the darkest of them. I'm not sure which I like most, but Oxblood is certainly the richest of them. 

Here's the video review for it's water-resistance. It's not very water resistant. It leaves a bit behind, but it's not one that I would call anything near water-resistant. 

It's a little more expensive than the Noodler's inks, at $12.75 for an 80ml bottle instead of $12.50 for 90ml, but if you wanted to make up that lower volume of ink you could dilute the ink a little. It's got the saturation to support that kind of thing if that's what you're into.
