Fountain Pen Ink Guide for Beginners: Colors, Properties, and Brands

One of the great joys of fountain pen ownership is the ink. Hundreds of colors exist, from practical blacks and blues to exotic teals, burgundies, and shimmering golds. Choosing your first bottled ink can be overwhelming. This guide covers the basics so you can start exploring with confidence.

Ink Types

Dye-Based Ink

The most common type. Dye-based inks are made from water-soluble dyes dissolved in water. They flow well, are easy to clean, and come in an enormous range of colors.

Pros: Wide color selection. Easy to clean. Safe for all fountain pens. Available everywhere.

Cons: Not waterproof. Can fade with prolonged light exposure. Stains can be difficult to remove from clothing and skin.

Pigment-Based Ink

Uses solid pigment particles suspended in a liquid carrier. More permanent and water-resistant than dye-based inks.

Pros: Water-resistant to waterproof. Fade-resistant. Good for archival documents and outdoor use.

Cons: Can clog pens if not used regularly. Requires more frequent pen cleaning. Limited color range compared to dye-based.

Recommended for beginners? No. Start with dye-based inks and explore pigment later.

Iron Gall Ink

A traditional ink type dating back centuries. Creates a permanent line through a chemical reaction with paper. Darkens over time.

Pros: Permanent. Beautiful aging properties. Historical significance.

Cons: Acidic. Can damage pens if left in them for extended periods. Requires specific maintenance. Not recommended for beginners.

Shimmer Ink

Dye-based ink with fine metallic particles added. Creates a glittering effect on the page that is stunning on good fountain pen paper.

Pros: Beautiful, unique effect. Fun and festive.

Cons: Particles can clog feeds and nibs. Requires extra cleaning. Not for everyday use in fine nibs.

Ink Properties to Understand

Shading

The variation of light and dark within a single stroke. As the nib moves, it deposits more or less ink depending on speed and pressure, creating a gradient effect. Some inks shade dramatically (Pilot Iroshizuku Ku-Jaku), others shade minimally (most black inks). Shading is one of the most beautiful properties of fountain pen writing.

Sheen

A secondary color that appears on the surface of the ink when applied heavily. Organics Studio Nitrogen appears blue on the page but has a red-copper sheen. Sheen is visible on smooth, non-absorbent paper (like Tomoe River) and almost invisible on absorbent paper.

Saturation

How intense the color appears. Highly saturated inks are bold and vivid. Desaturated inks are subtle and muted. Personal preference determines which you prefer.

Dry Time

How quickly the ink dries on paper. Fast-drying inks (under 5 seconds) are practical for daily use. Slow-drying inks (15+ seconds) risk smearing but often have better shading and sheen properties.

Flow

How wet or dry the ink feels. Wet inks flow generously, producing thick lines and rich color. Dry inks flow sparingly, producing thinner lines and less color. Most pens have a preferred flow range — wet inks in a wet pen can be too much; dry inks in a dry pen can skip.

Recommended Starter Inks

Safe and Reliable

Waterman Serenity Blue — A classic blue that behaves perfectly in every pen. Well-lubricated, moderate flow, quick drying. If you buy one ink, this is a strong choice.

Pilot Iroshizuku Take-Sumi — A rich, professional black with beautiful shading. More interesting than a flat black but still workplace-appropriate.

Diamine Oxblood — A deep, warm red-brown that is more unique than basic colors but still versatile. Excellent shading.

Beautiful and Well-Behaved

Pilot Iroshizuku Kon-Peki — A vivid cerulean blue that is almost universally loved. Outstanding shading. The ink that has converted many people to the fountain pen hobby.

Diamine Earl Grey — A sophisticated medium gray. Understated and elegant. Beautiful in fine nibs.

Robert Oster Fire and Ice — A complex teal that shifts between blue and green depending on nib size and paper.

Best Value

Diamine (any color) — Diamine offers over 100 colors at prices significantly below Pilot Iroshizuku and other premium brands. Quality is consistently good. The 30ml bottles are perfect for trying new colors without a large investment.

Ink Samples

Before buying full bottles (typically 50-80ml), try ink samples. Many retailers sell 2-3ml samples that let you test a color without commitment. A sample fills a converter two to three times — enough to know whether you like the color, flow, and behavior.

This approach lets you try a dozen inks for the cost of one bottle. It is the most cost-effective way to explore.

Ink Care and Storage

• Store bottles upright in a cool, dark place.
• Close bottles tightly to prevent evaporation.
• Do not mix inks from different brands in a pen (chemistry can be unpredictable).
• Clean your pen when switching inks — flush with water until clear.
• Ink does not expire, but very old ink may develop mold. If you see floating particles, discard it.

Building Your Collection

Start with one or two bottles in colors you will use daily. A blue or blue-black for work, and something more expressive for journaling. As you learn your preferences — wet or dry, saturated or subtle, practical or playful — expand your collection deliberately.

The rabbit hole is deep. Fountain pen ink is a hobby within a hobby, and the range of available colors and properties is nearly infinite. Enjoy the exploration.
