Diamine Blue/Black Ink Review

I’ve already shared my love for fountain pen inks made by British manufacturer Diamine. My favorite of their inks is their Blue/Black. I have more blue-blacks in my collection than any other color. I don’t really dislike any of them. However, I seem to always come back to this basic color from Diamine.

Diamine Blue/Black is a well-behaving color that sits right in between blue and black. I do a lot of journaling, and it’s my daily go-to for that. Blue/Black can shade fairly well. When pooled, it gets fairly close to black. It flows freely through every pen I’ve tried. It goes down wet on a wide range of papers. It’s a color that works well for office applications. I highly recommend it.
