Diamine Ink for Fountain Pens - 80 ml Bottle - Oxblood Red

Diamine's "Oxblood" is a very dark maroon/burgundy color. On glossy bright white paper, it'll be an amazing nearly-dry blood color, especially if your pen is wet enough to have it bead up nicely at the ends of strokes. On matte paper, where colors always look darker, it'll be a reddish-black (the color of a ripe dark cherry's skin.)

It reminds me of the "Burgundy" color of the Marvy/Uchida Calligraphy markers. It's darker than the Kuretake Zig Letter Pen CocoIro's "Bordeaux" color (which JetPens sells as "blood red".)

I think this is the darkest red in the current Diamine range. If you want a red that's a little more vivid, you might consider Diamine's "Maroon".

The bottle is, as expected, heavy glass with a hard plastic cap, but note that you might not get the marbled green cap shown in the photos here -- my bottle has a solid black cap.

Amazing burgundy colour. It's been lauded as an ink that really looks like blood, and I have to agree. Think Diamine Syrah and Red Dragon mixed with a little bit of Waterman Havana brown. Note that when it's smeared, there's a bit more purple in the red than what you'd expect from actual blood, but the effect when concentrated is stunning.

It feathers a little bit on really, really cheap recycled papers, but otherwise it's very well behaved. It's dark enough on any paper that it doesn't look like correction or notation ink.

Oxblood color is true to its name. It is a dark purple-y, red. On white and ivory paper the color is saturated. This isn't exactly the color I was looking for, but I got exactly what I bought. I'm still looking for a deep, dark red without purple or brown undertones.
