Your Guide to Blending Coloured Pencils

You've learned how crucial layering is for building rich colour in the previous page in this core techniques hub.

Now, let's tackle the next step many artists find tricky: blending.

Blending is simply the process of smoothing the transitions between colours or values to create a seamless look. When done well, it raises your work, making textures look softer and forms appear more realistically rounded.

If you've ever struggled with unwanted pencil lines, patchiness, or harsh edges, understanding blending techniques can make a huge difference.

It's important to remember two things first:

• Blending works best when you have enough light layers of pencil pigment already on the paper for the tool to work with. Don't try to blend a single, sparse layer!
• You don't have to blend everything! Sometimes the texture of pencil strokes is desirable. Blending is a tool to use purposefully where you want a smoother effect.

Let's explore some of the most common and effective blending methods.

Method 1: Paper Stumps and Tortillons - The Artist's Secret Weapon?

These simple tools, made from tightly rolled or compressed paper, are invaluable for coloured pencil artists.

Stumps: Denser, usually pointed at both ends, available in various sizes. Good for larger areas and smooth blends.

Tortillons: Tightly rolled paper, pointed at one end. Often better for smaller areas and more subtle blending.

How to Use Them: Stumps and tortillons allow you to gently move pencil pigment, softening edges and creating smooth transitions without adding more colour.

• Gentle Touch: Use a light hand! Gently rub the tool over the layered pencil area. Rubbing too hard can lift pigment or even damage the paper or the tortillon tip.
• Suitable Pencils: They work particularly well with softer core pencils (like Prismacolor Premier or Derwent Coloursoft) but can also be effective with harder pencils (like Polychromos) if enough layers are applied.

Alternative Use (Palette Transfer): You can create a small palette of colour on scrap paper, lift the pigment with your stump, and then apply it gently to your artwork for very smooth base layers or subtle tints.

Tips and Maintenance

• Keep them Clean: Wipe tips on scrap paper or fine sandpaper often to avoid muddying colours.
• Separate Stumps: It's wise to keep separate stumps for different colour families (e.g., blues/greens, reds/yellows) and especially separate ones for graphite/charcoal vs. coloured pencil.
• Cleaning: For deeper cleaning, gently rub the dirty tip on fine sandpaper or an emery board. You can sometimes refine the point carefully with a craft knife if needed (adult supervision recommended!). Don't use a pencil sharpener.
• Avoid Sanded Paper: Using these tools directly on very abrasive sanded art papers can fray them quickly.

Method 2: Specialty Colourless Blender Pencils

These look like regular pencils but are made primarily of wax or oil binder without any pigment. Popular examples include the Prismacolor Colorless Blender, Lyra Rembrandt Splender Blender, and Derwent Blender Pencil.

• How they work: They physically blend and merge the existing coloured pencil layers using pressure, without adding colour themselves.
• Technique: Apply the blender pencil over your layered colours using medium to firm pressure. Work in small circles or follow the contours.
• Pros: Don't alter the hue of your underlying colors significantly. Designed specifically for blending. A dry method offering good control.
• Cons: Can sometimes create a slightly waxy look depending on the brand and paper.

Quality and hardness vary between brands (e.g., Lyra Splender is known for being softer, Prismacolor matches their pencil softness). Importantly, using firm pressure with these can start to flatten the paper tooth, similar to burnishing, making further layering difficult.

Method 3: Using Light Coloured Pencils

You can also blend colours by layering a white or very light-coloured pencil (like cream, ivory, or a pale grey) over your existing layers with increasing pressure.

• How it works: The light pencil physically mixes with the layers beneath and helps to smooth them together.
• Technique: Apply the light pencil with medium to heavy pressure over the area you want to blend.
• Heads Up: When you use heavy pressure with a light pencil like this, you are essentially burnishing. This creates a very smooth, polished look but also seals the paper tooth, making it hard to add more layers.
• We cover this technique in detail on the very next page - Burnishing Explained. 

Method 4: Solvents (Use with Care)

Solvents are liquids used to dissolve the binder in coloured pencils, allowing the pigment to flow and blend, often creating painterly effects.

While they can be very effective, this is a method that requires significant caution, thorough testing, and a good understanding of safety practices.

!! Test First, Always !! 

Before ever applying any solvent to your precious artwork, it's crucial to test it on scrap paper with the exact same pencils and paper you plan to use for your piece. Different solvents can react differently with various pencil brands and papers, sometimes even changing colours. This step is non-negotiable!

A Beginner-Friendly Option: Zest-It Pencil Blend

If you're new to solvents, a product like Zest-It Pencil Blend is often recommended as a starting point.

It's a citrus-based solvent (derived from orange terpenes) designed for artists, and it's non-toxic, non-flammable, biodegradable, and generally leaves no residue. Its primary function is to dissolve the wax or oil binder in your pencils.

Another Accessible Option: Solvent Pens

For a more controlled application, you might consider pre-packed solvent pens (e.g., from Tombow, Derwent, or Finesse).

These fibre-tipped pens contain a small amount of solvent (often alcohol-based) and allow for more precise application, which can be less intimidating for beginners.

How to Apply (General Technique)

• Apply solvents sparingly. A little goes a long way.
• Use a cotton bud, a small, stiff brush, or even a dedicated paper blending stump to apply the solvent to your layered pencil work.
• Gently move the pigment to blend colours and smooth transitions.

Key Things to Know

• Pros: Can create beautiful, smooth, painterly blends, especially effective for large areas or heavily layered pencil.
• Cons and Cautions: This is a wet method, so it can affect your paper (test for buckling!). Solvents can sometimes alter the colour balance of pigments. The blended area might dry to a matte finish. Ensure the area is completely dry before adding more pencil layers.

Safety is Paramount

• ALWAYS work in a well-ventilated area, even with low-odour or non-toxic solvents.
• Avoid skin contact: consider wearing gloves.
• Follow all manufacturer instructions and dispose of used materials (like cotton buds or paper towels soaked in solvent) safely, according to product guidelines.

Recommendation

Given the precautions needed, I generally advise artists to become comfortable with dry blending methods (like stumps and blender pencils) first.

Solvents offer unique effects but come with a greater need for careful practice and safety awareness.

Other Tools (Brief Mention)

• Cotton Swabs/Buds: Can be used for very soft, gentle blending, but be careful as they can lift colour unevenly. Best for light applications.
• Felt/Chamois: Small pieces can be used for soft, gentle rubbing to blend colours subtly.

Which Blending Method Should You Use?

The best method often depends on the effect you want, the pencils you're using, and your paper:

• For subtle smoothing and control: Stumps/Tortillons are great.
• For dry integration and richer colour: Colourless Blender Pencil works well.
• For a final, polished look (seals paper): Burnishing with a light pencil (see next page!).
• For painterly effects or heavy layers: Solvents (used carefully).

Remember: Successful blending always starts with good layering. If you're experiencing issues like patchiness, check out the Troubleshooting Common Issues page.
