DeAtramentis makes some interesting inks, and usually they have good behavior and handling characteristics. This ink conforms in that regard. This is a very reddish-brown, it's almost to my eyes more reddish than brown. I find it hard to define as sepia, but that's what the maker calls it. I'm not much for red or reddish inks as I personally have little use for them, while brown is an ink color whose appeal is hard to deny.
You may personally really like this color. But not for me, so it's hard for me to get excited about the ink. I think the color is appearing a bit dark for the actual ink, as it seems lighter on the paper compared to the screen.
But it handles quite well. Somewhat water resistant, in that the red washes away, leaving some of the brown behind.
The usual papers appear here: MvL=Mohawk via Linen, Hij=Hammermill 28lb inkjet.
