I’ve always loved using colored pencils for their simplicity and control. Whether I’m sketching in a coffee shop or layering soft shadows over a nature journal page, there’s something incredibly satisfying about how they glide across paper. But a question I kept coming back to was: how are colored pencils actually made?
That curiosity led me down a rabbit hole. I had used them for years without realizing what goes into crafting a pencil that blends well, holds its point, and delivers rich color. So if you've ever wondered how colored pencils are made, from pigment to pencil tip, this post walks you through it in a personal and grounded way—no manufacturing jargon, just what I found useful and surprising as an artist who likes to understand the tools I use.
I studied traditional 2D character animation at CalArts, where observation and expressiveness were core to how we approached drawing. I still carry that mindset: I draw what I see, starting with large forms shaped by light and shadow, then work my way to details. That kind of drawing demands materials that respond well to layering, pressure, and gesture—which starts with understanding how those materials are built.
Key Points
- The pigment blend and binder ratio directly affect how easily a pencil lays down color and blends with others.
- Higher-quality pencils use less filler and more pigment, which matters a lot when layering or burnishing.
- Wood casing isn’t just about aesthetics—it affects how smoothly the pencil sharpens and whether the core breaks easily (or constantly).
How Colored Pencils Are Made: From Raw Ingredients to Finished Tool
Colored pencils might seem simple on the surface, but there's a full behind-the-scenes process that determines their quality and feel. It all starts with pigment.
Pigment and Binder: The Core Ingredients
The vibrant core of a colored pencil is made from two main components: pigment and a binder. The pigment is the actual color, while the binder holds everything together in a solid, usable form.
In artist-grade pencils like those found in many colored pencil sets, the pigment is highly concentrated, with minimal filler. That’s why some pencils blend smoothly and others feel chalky or weak. The binder can be either wax- or oil-based, and that single choice changes everything—from texture to layering to how the pencil interacts with the paper.
Wax-based cores are more common. They have a soft, creamy feel and are easier to blend. But they can develop a dull finish over time (called wax bloom) if you use heavy layers.
Oil-based cores, like those used in Faber-Castell colored pencils, tend to be harder and cleaner in their layering. They also hold a sharper point longer. This makes them a great match if you're doing controlled drawings or want to avoid constant sharpening.
Depending on the ratio of pigment to binder, you'll get either a soft, buttery pencil or a harder one that keeps its point. This affects everything from layering to blending and even erasing. I go into more detail about those techniques in my post on how to use colored pencils.
Shaping and Extruding the Core
Once pigment and binder are mixed into a thick paste, the material is shaped into long, spaghetti-like strands called leads. These are formed using a machine that extrudes the paste through a die, ensuring consistency in size.
The drying process is delicate. Dry them too quickly and the core becomes brittle. Too slowly and the material stays soft. Most manufacturers let them dry under controlled humidity and temperature so the cores are stable for casing.
These tiny choices—dry time, pressure, binder—all impact how a pencil behaves once it's in your hand. If a pencil constantly breaks while sharpening, this stage might be where it went wrong.
Encasing the Core in Wood
This is where the pencil becomes a pencil. The dried core is carefully laid into a grooved wooden slat. A second slat goes on top, and they are glued together in a sandwich.
Once the glue sets, the slats are cut into individual pencils. They’re shaped, either round, hexagonal, or triangular depending on the brand and grip design.
The type of wood used also matters. High-end pencils often use cedar, which smells good and sharpens smoothly without splintering. In contrast, cheaper pencils use composite wood or plastic blends, which can dull your blade fast and crack unpredictably.
I've written more about this in my breakdown of the best pencil sharpener for colored pencils if you want to make your tools last longer.
Painting, Dipping, and Labeling
After the pencils are shaped, they’re painted with a finish, dipped to show the end color, and stamped with brand information.
Just a heads up: the color on the end of the pencil doesn’t always match the pigment inside. Some brands are better at this than others. I usually test them on a scrap of the best paper for colored pencils before starting a drawing, especially for something layered or realistic.
Why It Matters When You're Drawing
When I draw expressively, I build up marks and tones in a way that relies on feel—how the pencil responds when I change pressure or scribble loosely into shadows. A poor-quality pencil breaks the flow.
There were times I couldn’t figure out why my colors felt muted or why the layers weren’t building up. Turns out, it was the pencil itself.
Understanding the materials changed everything. I adjusted the types of pencils I use based on whether I want control or softness. I also started experimenting with burnishing as a finishing layer to push colors further.
If you’re just starting out, my post on using colored pencils for beginners might help you avoid the same frustrations I had.
Oil vs. Wax Cores: What That Actually Feels Like
The difference between oil- and wax-based cores isn’t just technical—you really feel it when you're drawing. Wax cores are great for blending and soft coverage. They're the ones I use when sketching a sunset with colored pencils or layering expressive color for a botanical study.
Oil-based pencils feel firmer, stay sharp longer, and give crisp edges. They’re great for crosshatching, detailed patterns, or sketching animals from photo references where texture matters. If you like layering but hate wax bloom, oil pencils are your friend.
Some artists mix both. If you’re experimenting with mixed media like colored pencils and watercolor or even colored pencils and markers, knowing what type of core you’re working with really helps.
You can go even further with watercolor colored pencils, which behave like regular pencils when dry, but react to water for painterly effects. These are great for travel sketching and loose expressive work.
Sharpening and Paper Make a Difference Too
If your pencil keeps breaking or feels scratchy, it might not be the pencil—it might be your sharpener or your paper.
I didn’t realize how much this mattered until I started using a sharpener designed specifically for softer, artist-grade cores. A cheap sharpener can tear the core or cause splintering.
Your paper choice also affects results. Toothy paper helps with layering, but too much texture can cause those frustrating white gaps. I explain how to avoid that in how to color with colored pencils without white spots.
Curious About Different Types?
There are tons of options beyond your standard wax-core pencil.
You can try erasable colored pencils for sketching and revisions. I often use Ticonderoga erasable colored pencils for planning compositions loosely before committing to stronger lines.
There are also colored pencils with erasers built in, which are handy for sketchbooks or travel kits.
