Top 5 Blue Fountain Pen Inks: Five Shades That Earn a Spot in the Rotation

Introduction

Blue versus black is one of the oldest debates in fountain pen circles. An informal poll of general users showed black winning by roughly two thirds, which is surprising given how much personality blue brings to the page. Blue ink once mattered for a practical reason: it stood out from printed black text when verifying original signatures. Printers and scanners have made that argument largely obsolete, but blue still offers superb contrast against black print, which makes it a joy for note taking. More importantly, the range is enormous. Here are five blue inks that each earn their place for a very different reason.

Why Blue Still Deserves the Spotlight

What makes blue so rewarding is the depth and variety within the color family itself. There are blues that read almost black, bright turquoise-leaning shades, and saturated sapphires that seem to glow on the page. The five inks below barely scratch the surface of what is out there, but together they show just how wide that spectrum runs.

Montblanc Midnight Blue: The Profoundly Dark Favorite

Montblanc Midnight Blue is one of those inks that behaves like a black with a secret. It is so profoundly dark that the pen feels full of black ink, yet the nib delivers a suggestion of blue in the highlights and on the different strokes. That subtle blue-black interplay gives writing a sense of authority and presence, with strong contrast and deep dark tones across the page. If you want a bit of mystery in your writing and a shade that mixes blue and black beautifully, this is a brilliant pick.

Krishna Moon View 2: The Show-Stopping Sheen

Krishna’s Moon View 2 comes from one of the most admired producers of sheening inks in India. It has a beautifully saturated blue base, almost a sapphire, topped with a sheen of fuchsia molten red that looks intensely metallic on the page. It is one of the most striking sheening inks around. Because it is a sheening ink, it is best kept in pens that are easy to field-strip and clean rather than anything delicate. Where it shines is correspondence and notes, anywhere you want the page to look genuinely magical.

J. Herbin Eclat de Saphir: The Default Blue

J. Herbin Eclat de Saphir is a gorgeous, saturated sapphire blue that earns the role of default ink in many collections. It flows wonderfully, looks gorgeous on the page, and hits a sweet spot of contrast and saturation that makes handwriting look its best. It is the kind of ink people ask about: a beautiful shade of blue that draws questions every time it appears on paper. As a pleasant, dependable, everyday blue, it is an absolute classic.

Pilot Iroshizuku Kon-peki: The Reliable Turquoise

Could any blue list skip Kon-peki? This is a delightful robin’s egg blue in the turquoise range, light and beautiful yet with tremendous presence and contrast on the page. It is eminently usable and behaves perfectly in any fountain pen. It even works as a control ink: fill a misbehaving pen with Kon-peki, and if it writes well, the pen was fine all along. This is a blue that makes writing sing off the page.

Taccia Hokusai Kai: The Aquatic Newcomer

Taccia Hokusai Kai is a natural dye ink from Japan, sold in some of the most beautiful packaging around, printed with Hokusai’s Great Wave off Kanagawa. The ink itself is as wet and free-flowing as that wave: a beautiful dark aquatic blue with lighter tones above, giving it a striking aquatic look and superb contrast. The interesting part is a breath of pinkish sheen that reads on the page like a drop shadow, lending writing a subtle three-dimensional effect that deepens the contrast even further. It is a mysterious, beautiful blue that grows on you quickly.

Which One Wins?

Every one of these five is fantastic and each is completely different. Midnight Blue is beloved for its darkness and goes into every pen it can. Moon View 2 is an incredible ink, though its sheening nature limits it to inexpensive, easy-to-clean pens. Kon-peki is adored for its turquoise tones and its willingness to flow where other inks struggle. Eclat de Saphir is the default blue. And Hokusai Kai, the newest of the group, is adored for its Hokusai association and sheer distinctiveness.

Conclusion

If forced to pick just one, the narrow winner is J. Herbin Eclat de Saphir, and only by a hair’s margin. It is the default, the ink that goes into any pen when nothing else seems right, and it is close to being a signature ink in its own right. The real takeaway, though, is the range: five blues, five completely different characters on the page. The right choice depends on whether you want authority, shimmer, dependability, cheerfulness, or a touch of the ocean.
