There are no official rules or classifications of what is or isn’t a blue black ink, but in general, blue black inks can be divided into the following color groups.
Neutral Blue Blacks
These inks are what most people think of as blue black: a dark blue-gray.
From left to right: Kaweco Midnight Blue, Lamy Blue Black, Pelikan Edelstein Tanzanite, Pilot Iroshizuku Shin-kai, and Sailor Jentle Blue Black.
Black-leaning Blue Blacks
Some blue blacks lean more heavily towards black or dark gray, with only a faint hint of blue.
From left to right: Caran d’Ache Magnetic Blue, Diamine 1864 Blue Black, and Monteverde Blue Black.
Blue-leaning Blue Blacks
On the other hand, some blue black inks resemble a medium or royal blue with just a slight cast of black or gray.
From left to right: J. Herbin Bleu Nuit, Pilot Blue Black, and Platinum Blue Black
Teal-leaning Blue Blacks
Some blue black inks look more like a grayish teal blue than a “pure” blue black. Since many of the inks in this color group are made by older fountain pen ink brands, some people refer to these inks as classic or vintage blue blacks.

Tone (also called value, lightness, or shade) refers to how light or dark a color is.
Darker inks like Diamine 1864 Blue Black provide high contrast, helping words to stand out clearly, while lighter colors like J. Herbin Bleu Nuit can create a more subtle or informal feel.
Water resistance is the ability of an ink to not fade or spread when exposed to water. Few fountain pen inks are truly waterproof, but many have enough water resistance to remain legible after a brief wetting.
We tested each ink to see how well it would survive being dipped in water for about 30 seconds.
Sailor Nano Sei Boku is almost completely waterproof, and both Pilot Blue Black and Platinum Blue Black have high water resistance.
Inks with moderate water resistance include Caran d’Ache Magnetic Blue, Kaweco Midnight Blue, Lamy Blue Black, Pelikan Edelstein Tanzanite, Pilot Iroshizuku Shin-kai, and Sailor Jentle Blue Black.
Shading is the property of many fountain pen inks to pool more heavily in some parts of a line or letter, creating interesting variations in tone and color.
Shading is most common among lighter, more colorful inks, while most black and medium blue inks have very little or no shading. Blue black inks, however, often have just enough shading to add a touch of interest without being distracting. We used Kaweco Midnight Blue in the above demonstrations.
If you’re looking for an ink that will stand out from the crowd while still being appropriate for any occasion, a blue black ink may be just what you need. Do you have a favorite blue black ink? Let us know in the comments below!
