This ink has an incredible amount of depth when using an italic nib. The colors of this ink look even more incredible on Moleskine paper, since it is ivory colored.2 This ink is extremely comparable to Waterman's Havana. At first glance on paper, the ink looks brown, but upon further inspection proves to have a stunningly deep mix of colors. It could be compared to Private Reserve's Black Cherry, but that ink has very little shading, despite that it looks much more like a dark red. Noodler's Red-Black is definitely not a dark red, but exactly as its name states, a 50/50 mix of red and black. This is my favorite ink for writing letters and for note taking as well. This is not a color that I ever expect to be able to find in any rollerball pen and is so unique that every word I write seems just as unique and deep.
Walking into class on a snowy day, I accidentally dropped a vocabulary sheet on the ground and minutes later found it under my wet shoe. The red ink was running down the page and away from the letters I had written, but the black appeared to stay in place. I believe that the black in this ink is bulletproof and the red is not, as is common in many of the colored Noodler's inks that are bulletproof.
At times, this ink can look like almost like a blood red. Not, that I'm a morbid person, but I think it's one of the coolest colors I have encountered. Fans of poorly written vampire novels (Twilight Series) rejoice! Now you too can write vampire love letters in "blood", as vampires did before texting.
