Colouring Pens: How to Choose the Right Nibs and Ink

Colouring pens aren’t just about the number of colours printed on the box. A generous palette can hide shades that are too similar, a fragile nib, or ink that bleeds through the page. Whether you’re into adult colouring, school projects, lettering or manga illustration, a few technical criteria can help you avoid disappointing purchases.

Common Pitfalls Before You Buy

1. Confusing colour variety with versatility

A set of 36 or 48 shades won’t necessarily suit every purpose. Fine-tip pens are perfect for outlines and tiny details, but they fill large areas slowly. Conversely, a broad tip covers a zone quickly, at the expense of precision.

To vary your uses without buying multiple sets, dual-tip pens combine a fine tip and a wider tip in one tool.

2. Overlooking the ink type

Water-based pens are very common for writing, schoolwork and colouring on paper. They’re generally easier to clean, but the result depends heavily on the paper weight. On paper that’s too thin, the ink can make the page buckle or show through on the reverse.

Acrylic pens offer a finish close to paint, often opaque, and can be used on various surfaces such as wood, glass, ceramic or canvas. However, they don’t replace classic pens in every situation: you need to check their drying time, adhesion and compatibility with the surface.

3. Forgetting about storage and capping

A nib that dries out quickly turns a set into an expensive purchase. After each session, caps must be replaced properly. Some brands also recommend horizontal storage, particularly to ensure a consistent ink flow. Heat, direct sunlight and porous surfaces can also damage your equipment.

Technical Criteria to Check

Nib shape

  • Fine tip: outlines, details, annotations, precise patterns and manga.
  • Medium tip: writing, everyday colouring and filling small areas.
  • Brush tip: variable width depending on pressure, calligraphy and illustration.
  • Chisel or broad tip: quick coverage and large colour areas.
  • Conical tip: consistent line and easier grip for beginners.

For lettering, brush-tip pens require a bit of skill, but allow you to create more expressive thick and thin strokes. For colouring with intricate patterns, a combination of fine and medium tips often proves more practical.

Intended surface

Thick colouring paper reduces the risk of ink bleeding through. For a standard notebook, choose a formula advertised as bleed-resistant and test it on a similar page. Markers designed for adult colouring can produce intense colours, but multiple passes over the same spot can still saturate the paper.

Drawing markers intended for arts and crafts should be tested on an inconspicuous area when used on wood, glass, metal or a varnished surface. Metallic pens are useful for decorative touches, but their visibility can vary depending on the colour of the surface.

Grip and storage

A triangular barrel or a contoured grip zone can make long sessions more comfortable. Also check the readability of the colour code and whether a reusable box is included. For children over 3 years old, caps remain small parts: adult supervision is recommended, in line with the warnings on product sheets.

To Complete a Pen Set

Metallic pens add details that stand out on both light and dark paper. Watercolour pencils, meanwhile, let you move from a dry line to a diluted effect with a brush and a little water. For large areas of colour, a broad tip or a chisel-tip marker will be more comfortable than a fine tip.

If you use your pens regularly, organise colours by family, note down the references you’ve used and keep a test sheet. This method avoids duplicates and lets you check the finish before committing to a whole page.

FAQ on Colouring Pens

Do water-based pens bleed through paper?

They can bleed through thin paper, especially after several passes. Always test a colour on a page of equivalent weight. Thicker, less absorbent paper generally reduces the risk, though it doesn’t eliminate it completely.

Which tip should I choose for adult colouring?

A medium tip works for most areas. A fine tip is useful for detailed patterns, while a brush tip offers width variations and a more artistic finish. A dual-tip set can save you from buying several ranges.

How can I extend the life of my markers?

Replace caps immediately, avoid heat and direct sunlight, and follow the manufacturer’s storage instructions. For some water-based or acrylic pens, horizontal storage is recommended. Also avoid pressing the tip against a surface for too long to prevent it from becoming crushed.
