Watercolour Pencils: How to Choose the Right Set for Your Practice

Watercolour pencils let you move from precise drawing to a wash effect with just a damp brush. This versatility appeals to illustrators, art students, travel-journal enthusiasts, and anyone who wants to lighten their kit when sketching on the go. But not all sets are created equal, and not every one suits the same purpose.

Before you buy a box of watercolour pencils, there are a few pitfalls worth watching out for.

Common Pitfalls When Buying

  • Relying solely on the number of colours: a set of 72 shades isn’t necessarily more practical than one of 12 or 24. When the hues are too similar, a good number of pencils may end up sitting unused at the bottom of the box.
  • Confusing water-soluble pigments with ordinary pencils: some standard coloured pencils can be slightly diluted, but they won’t give you a true watercolour effect. Make sure the lead is clearly described as water-soluble.
  • Overlooking the paper and accessories: paper that’s too thin will quickly buckle when it meets water. Likewise, a set without a brush may mean you have to buy an extra accessory if you want to start using the wet technique straight away.
  • Taking a promise of permanence as a universal guarantee: lightfastness depends on the pigments, the paper, the exposure and the storage conditions. Check the details for each specific product rather than assuming it applies to an entire range.

Technical Criteria to Check

1. Solubility and Lead Behaviour

Good watercolour pencils should work in two ways: dry, for outlines, hatching and details, and then with water, to spread the colour and create gradients. A lead that’s too hard can leave marks that are difficult to blend. A softer lead deposits more pigment, but it’s also more likely to break if the wood or bonding isn’t sturdy enough.

For a travel journal or quick studies, go for a smooth application and a box that’s easy to carry. For detailed illustration, point retention and pigment consistency matter most.

2. Number of Shades and Palette Logic

The 12, 24, 36, 48, 72 or 120 colour formats suit different uses:

  • 12 colours: a compact starter set for learning to mix shades while keeping your budget in check.
  • 24 colours: a very practical compromise for illustration, classes and sketchbooks.
  • 36 to 48 colours: more intermediate shades for landscapes, portraits and regular practice.
  • 72 or 120 colours: an extensive palette for those who want to minimise mixing and have as many variations as possible right to hand.

A smaller palette is perfectly fine if you’re confident with mixing. On the other hand, a large set can save you time on projects that need specific shades immediately available.

3. Packaging, Lead and Storage

A metal tin protects a small set well and is ideal for travel. A wooden box offers more compartments and a more refined presentation, but it’s often bulkier. Sets supplied in a cardboard box are generally easy to store, but they offer less protection against knocks.

Product listings may also mention a thick lead, reinforced bonding or pigments described as lightfast. These details are useful for comparing products, but don’t treat this feature as a guarantee of unlimited exposure. After use, let damp accessories dry and store the pencils in a dry place away from direct sunlight.

Usage Tips to Keep Your Pencils in Good Condition

Use a watercolour paper that’s thick enough to absorb water without warping. You can colour in dry and then apply water to the area, or lightly dampen the paper before adding the pigment. Rinse the brush between colours to avoid muddy mixes.

Let the pencils and brush dry before closing the box. Storing them in a closed container, in a dry place away from a very sunny window, helps protect the wood, the leads and the pigments.

Frequently Asked Questions About Watercolour Pencils

How do you use watercolour pencils with a brush?

First, draw or colour on the paper, then run a slightly damp brush over the area. Start with a small amount of water: it’s easier to add more than to rescue a soaking wet sheet. A set with a brush, like the Faber-Castell 24-pencil set, lets you get started straight away.

How long can you expect a set of watercolour pencils to last?

It depends on how often you use them, how much pressure you apply and the quality of your sharpener. A thick lead and reinforced bonding can help reduce breakage, but no pencil is unbreakable. Sharpen gradually and avoid dropping them. Put each pencil back in its box after use to protect the tip.

How many watercolour pencils should you buy to start with?

A set of 12 colours is enough to learn about mixing and discover the technique. A set of 24 colours offers more shades while staying compact. Sets of 36 colours and above become especially worthwhile when you practise regularly or want to spend less time mixing shades.
