How to Choose the Right Watercolour Pencils: A Buyer’s Guide

Watercolour pencils promise the best of both worlds: the precision of drawing and the fluidity of painting. But be warned, the market is flooded with products whose tempting promises quickly lead to disappointment. A pretty box isn't everything, and certain technical characteristics, often ignored, are crucial for achieving a result that lives up to your ambitions.

As the Head of Product Recommendations at Joybuy, my mission is to guide you through this jungle of options. This guide breaks down the pitfalls to avoid and gives you all the keys to choosing THE perfect set of watercolour pencils for you, whether you're a seasoned artist, a crafting enthusiast, or a parent looking for a gift to spark creativity in a young one.

The 3 Pitfalls to Avoid Before Buying

Don't be fooled by marketing. Here are three classic traps that turn a promising purchase into a regret:

  1. The "Professional Quality" Mirage: Many sets are labelled "professional" or "artist quality" when their pigment concentration is pitifully low. The result? Dull colours, a grainy dissolution, and a frustrating experience—a far cry from the desired watercolour effect.
  2. Quantity Over Quality: A set of watercolour pencils with 72 or even 120 pieces might seem like a steal. However, if the colours lack intensity and blend poorly, a more modest palette of 24 high-quality pencils will prove far more useful and versatile.
  3. Forgetting About Lightfastness: This is the flaw that's invisible at purchase but costs you dearly over time. Pigments with low lightfastness will cause your artwork to fade in just a few months if exposed to daylight. For a creation meant to be displayed, this is an absolutely non-negotiable criterion.

The Essential Criteria for an Informed Choice

To avoid falling into the trap, take a close look at these three characteristics that signify the true quality of a watercolour pencil.

1. Pigments and Binder: The Heart of the Colour

The quality of a watercolour pencil comes down to two things: pigment concentration and the nature of the binder. A high-end pencil is distinguished by a high density of fine pigments, ensuring rich and vibrant colours even when used dry. The binder, for its part, must be perfectly water-soluble so that the pencil stroke transforms into a smooth, even wash without leaving any grainy residue. Brands like Faber-Castell are renowned for their formulas that ensure flawless dissolution.

2. Lightfastness: The Guarantee of Longevity

Lightfastness measures the ability of pigments to resist fading over time when exposed to light. On professional watercolour pencils, this information is crucial. It is often indicated on the pencil barrel or packaging via a star system or a rating (like the Blue Wool Scale). High lightfastness is essential if you plan to sell, exhibit, or simply preserve your works. For recreational use or in a sketchbook, this criterion becomes less of a priority.

3. The Lead and Barrel: Your Assurance of Comfort

A lead that breaks with the slightest turn of a sharpener is the height of annoyance and waste. The lead's durability depends on its diameter and manufacturing process. Faber-Castell's SV (Secural Bonding) process, for example, bonds the lead to the wood along its entire length, making it much more resistant to impact. The diameter is also a key factor: an XXL lead like that of the Stabilo Woody 3-in-1 (10 mm) is perfect for watercolour pencils for children. It's nearly unbreakable and offers an excellent grip. For artists, a 3.3 to 3.8 mm lead represents the best compromise between strength and fine-line capability.

Frequently Asked Questions (FAQ)

What's the difference between watercolour pencils and classic coloured pencils? The entire difference lies in the lead's binder. The binder in watercolour pencils is water-soluble: when touched with a wet brush, it transforms a drawing into a watercolour-style painting. Conversely, classic coloured pencils use a non-soluble wax or oil-based binder, intended only for dry drawing.

Do you need special paper for watercolour pencils? Yes, it's essential for the wet technique. To get good results, opt for watercolour paper with a weight of at least 300 g/m?. It's designed to absorb water without buckling or tearing, unlike standard printer paper which would quickly become soaked. For dry use, however, any drawing paper will do.

How should I care for the brush that comes with watercolour pencils? If your box of watercolour pencils includes a brush, proper care will extend its life. After each session, rinse it thoroughly with clean water until no colour residue remains. Gently reshape the tip with your fingers and let it dry flat or hanging with the tip down. This prevents water from pooling in the ferrule (the metal part), which could loosen the bristles over time.
