When I first started sketching more seriously, I found myself torn between dry colored pencils and watercolor pencils. Both gave me color and texture without the mess of paint, but they behaved differently in ways I didn’t expect. If you're wondering about colored pencils vs watercolor pencils and which one gives you more control for observational drawing, I can share exactly what I've learned through years of experimenting with both.
I studied traditional 2D character animation at CalArts, where we focused a lot on expressive drawing, not just technical perfection. My drawing approach now is grounded in real-world observation, whether I'm sketching a tree, an owl, or a city street, I start by mapping out big shapes based on light and form. From there, I work loosely and intuitively, refining with smaller details and layers. I rarely block in with geometric shapes or follow a rigid formula.
So for me, control isn't about precision lines, it's about how easily I can guide a tool to follow what I see and feel. That’s where colored pencils and watercolor pencils show their differences in a big way.
Key Points
- Dry colored pencils give you instant, direct control for layering and detail work
- Watercolor pencils can be more unpredictable once water is added, but have unique blending advantages
- Your reference style and drawing surface should influence which tool you choose
Colored Pencils vs Watercolor Pencils: How They Respond to Observational Drawing
When I sit down to draw from life or a reference photo, I want my materials to keep up with my eyes. That means being able to quickly block in a shadow, capture the curve of a branch, or build up subtle color changes without fuss or second-guessing how the medium will behave.
With traditional colored pencils, like the ones in this set of best colored pencils for artists, I get an immediate response. The pigment is dry, predictable, and ready for layering. I can lightly sketch large shapes, slowly build up tone, and keep layering until I reach the effect I want. Nothing shifts or moves once it's down, which gives me the confidence to focus on observation.
You can see this in examples like my sunset with colored pencils, where gradual layering and subtle transitions in tone really mattered.
Watercolor pencils, on the other hand, give a very different kind of control. When dry, they feel like a slightly chalkier colored pencil, but once I add water, the pigment spreads and softens. This can be great for light washes, shadows, and atmosphere, but also unpredictable.
The water can dilute or over-activate areas you meant to stay dry. Lines you drew confidently can disappear or blur out. It can take practice and testing on scrap paper to feel comfortable using water. Still, there are ways to use them strategically, and I've broken that down in my guide to how to use watercolor colored pencils.
When Colored Pencils Give You More Control
For Detail, Texture, and Precision Layering
Colored pencils are unbeatable for dry texture and subtle detail. If I want to draw the bark of a tree, the fine strands in a bird's feathers, or the edge of a shadow falling across a subject’s face, I know exactly how the pencil will behave.
I can shade gradually, increase pressure to get darker values, or blend with other pencils by layering slowly. And because they stay put once applied, I can work in stages without disrupting earlier areas. That gives me control across the entire drawing process.
I also get more consistency by using the right tools. A good sharpener matters, especially when I’m working with soft-core pencils like Prismacolor or Faber-Castell. A dull tip can ruin the flow of a drawing, especially if you're trying to work into tight areas. I always recommend this best pencil sharpener for colored pencils that doesn't chew up the tips or break leads.
If you're new to layering or blending, check out techniques for coloring with colored pencils and this starter guide on how to use colored pencils. These are the things I wish I had learned earlier, especially about how to slowly build color rather than rushing in.
On Textured Paper or Canvas
Not everyone realizes this, but your surface can make or break how much control you feel. I always use paper with enough tooth to grab the pigment. Smooth paper might feel nicer to touch, but it doesn't hold pigment in layers the same way.
If you feel like your pencils aren’t performing the way they should, it might be your paper. Here's a guide to the best paper for colored pencils if you're not sure where to start.
Sometimes I like experimenting on different surfaces too – yes, even using colored pencils on canvas. It takes some adapting, but it's a good way to train your hand to respond to less forgiving textures. That process often makes me more deliberate and observant, even when I return to paper.
When Watercolor Pencils Offer Unexpected Advantages
For Loose Washes and Light Blocking
If you sketch loosely and prefer soft transitions or atmosphere over fine detail, watercolor pencils can offer a beautiful balance of control and spontaneity. I sometimes use them to quickly map out large shadow shapes or light direction before switching to dry pencil or ink.
When dry, the lines stay sharp. But when I apply a damp brush, those same marks dissolve into soft edges that mimic watercolor. This can be great for capturing clouds, reflections, or the light hitting a rock face.
I talk more about combining media and how watercolor pencils fit into mixed workflows in my guide on colored pencils and watercolor.
For Traveling or Quick Field Studies
One of my favorite uses for watercolor pencils is when I’m sketching outside or traveling. I can carry a small set, draw loosely in dry pencil, and activate select areas with a water brush or damp finger. That means no need for a separate watercolor palette.
It’s ideal for quick color studies or when I want to block in values without hauling around extra materials. This also makes watercolor pencils a smart pick for urban sketching, where speed and portability matter.
If you’re curious about starter techniques, I walk through basic approaches in my article on how to use watercolor colored pencils.
What About Blending and Erasing?
Blending is another area where control becomes a matter of preference and style. With dry colored pencils, I like using pressure and layering to get soft transitions. You can blend by overlapping colors, using blending pencils, or even using solvents, but personally I stick to dry layering.
One technique I return to often is burnishing. It involves pressing firmly with a light-colored or colorless pencil to blend layers together and flatten the texture. It takes some effort but gives a painterly, polished look.
If you hate seeing white specks between strokes, here's how I avoid that: how to color with colored pencils without white spots. Small changes in technique can make a big difference.
As for erasing, colored pencils aren’t forgiving. But there are workarounds. Some brands offer erasable colored pencils, and Ticonderoga erasables are surprisingly good for sketching. There are also colored pencils with erasers, which can help with planning or initial block-ins.
Still, I don’t expect to fully erase mistakes. I usually adjust by layering over or redrawing. That mindset has helped me loosen up and stay in the flow of observation rather than perfection.
A Personal Take: What I Reach for Most
I still use both, but if I had to pick one tool that gives me the most control in an observational drawing workflow, it’s dry colored pencils.
They let me react to what I see, whether it’s the shape of a bird in flight or the light bouncing off water. I can be slow, fast, expressive, or detailed. They respond well to how I want to draw in the moment.
I keep a variety of colored pencils sets nearby, especially the Faber-Castell pencils for their smooth layering and pigment quality.
