How to Choose Oil Pastels
Choosing oil pastels is easier when you know how pigment, binder, and softness affect color, blending, and control.
This guide explains the factors that matter most so you can match the right set to your style, surface, and budget.
What Are Oil Pastels?
Oil pastels are drawing sticks made from pigment, non-drying oil, and wax.
Unlike soft pastels, which rely on a dry chalky binder, oil pastels stay creamy and can be layered, blended, scratched back, and mixed with tools or solvents.
They are popular with beginners, illustrators, mixed-media artists, and plein air painters because they are portable and vivid.
Brands such as Sennelier, Caran d’Ache Neocolor II, Pentel, Holbein, and Cray-Pas each offer different textures and performance levels.
Key Factors to Consider When Choosing Oil Pastels
Pigment load and color intensity
High-quality oil pastels contain more pigment and less filler, which produces stronger color and better coverage.
If you want saturated strokes that stay vivid on paper, canvas, or board, look for sets known for strong pigment concentration.
Lower-cost sets can still be useful, but they may require more pressure to build color and can appear duller after layering.
For artwork intended for sale or archival display, pigment quality is one of the first things to evaluate.
Softness and texture
The softness of an oil pastel affects both feel and control.
Very soft pastels glide easily and blend smoothly, making them ideal for expressive work, gradients, and painterly effects.
Firmer pastels allow sharper lines, more detail, and less accidental smudging.
If you enjoy sketching, outlining, or layering fine details, a firmer stick may be easier to manage.
If you want thick, buttery color and easy blending, choose a softer formulation.
Blendability and layering performance
Good oil pastels should layer cleanly without becoming muddy too quickly.
Some brands excel at blending with a finger, stump, or colorless blender, while others hold their edges longer for textured marks.
Test whether colors can be layered from light to dark and dark to light.
This matters if you plan to create depth, shadows, or realistic transitions.
Artists who work in landscape, portrait, or still life often rely on layering behavior as much as color selection.
Staining, wax bloom, and drying behavior
Oil pastels do not dry like oil paint, but some surfaces and brands may develop bloom, a hazy film caused by waxes rising to the surface.
Better-quality pastels often minimize this issue, though storage and fixative choices also matter.
Some brands feel more permanent after application, while others remain highly movable.
If you need artwork with less smearing, look for a firmer set or plan to use a suitable fixative.
Choose Oil Pastels Based on Your Skill Level
For beginners
Beginners should look for a balanced set that is affordable, easy to handle, and forgiving.
A mid-range student set usually offers enough color variety without the steep price of professional lines.
- Choose medium-soft pastels for easier blending and control.
- Look for labeled lightfastness if the artwork will be displayed.
- Start with a smaller set, such as 12 to 24 colors, to learn color mixing.
For intermediate artists
Artists who already understand layering and composition can benefit from larger sets with stronger pigment and more nuanced hues.
At this stage, consistency between colors becomes more important than simply having many shades.
Consider whether the brand supports techniques you use most often, such as scumbling, impasto-like layering, or mixed-media work with acrylic ink, watercolor, or gouache.
For professional artists
Professional users often prioritize archival quality, pigment strength, and reliable performance across the full range.
Premium oil pastels from established art supply manufacturers tend to offer better lightfastness ratings, smoother application, and more stable color mixing.
If you sell work or exhibit in galleries, choose products with published pigment information and strong lightfastness data whenever possible.
What Surface Should You Use?
The surface you use affects which oil pastels perform best.
Smooth paper allows detailed marks, while textured surfaces grab more pigment and create a richer painterly effect.
Heavier paper, mixed-media paper, pastel board, illustration board, and canvas are all common choices.
- Textured paper: good for layering and visible stroke marks.
- Smooth paper: better for detail and clean edges.
- Canvas or board: useful for thick application and mixed media.
If you often work on dark paper, choose sets with strong opacity and bright highlights.
If you draw on toned paper, look for colors that contrast well and can build both shadows and highlights.
How to Compare Budget and Professional Sets
Price does not always equal suitability.
A budget set may be perfect for sketchbooks, classroom use, or experimenting with technique, while a professional set is better for finished work and archival results.
Budget sets are best when you need:
- Lower upfront cost
- Basic color selection
- Practice material for learning blending and layering
Professional sets are best when you need:
- Higher pigment concentration
- More consistent texture across colors
- Better lightfastness and longevity
One practical approach is to buy a small professional set in core colors and expand only after you know which hues you use most.
That prevents overspending on colors that sit unused.
How to Read Lightfastness and Product Labels
Lightfastness indicates how well a color resists fading with exposure to light.
For any work you plan to frame or display, this label matters.
Look for ASTM ratings, manufacturer lightfast charts, or clear permanence notes.
Also check whether the pastel names list actual pigment codes.
Pigment information helps you compare brands more accurately and understand why one yellow or blue may behave differently from another.
Which Brand Features Matter Most?
Different brands emphasize different strengths.
Sennelier is known for extremely soft, rich oil pastels.
Caran d’Ache offers controlled handling and strong color.
Holbein is often appreciated for a balanced feel, while Pentel and Cray-Pas may appeal to students and classroom artists.
Instead of choosing by brand name alone, compare these features:
- Range of hues in the set
- Softness and hand feel
- Opacity and blending behavior
- Lightfastness information
- Availability of open stock replacement colors
Open stock is especially useful because it lets you replace only the colors you use most.
This is valuable for artists who finish warm grays, whites, or skin tones faster than others.
Testing Oil Pastels Before You Buy
If possible, swatch the pastels on the paper you plan to use.
A color chart will show more than packaging ever can.
Compare how easily the sticks lay down color, how they layer, and whether the darkest tones stay clean when mixed with lighter shades.
When testing, look for these signs of quality:
- Uniform texture from stick to stick
- Strong color with little pressure
- Minimal crumbling or breakage
- Predictable blending across the set
Some art stores and online retailers show sample swatches or customer images.
These can help, but direct testing is still the most reliable method.
How Many Colors Do You Need?
The right set size depends on your workflow.
A compact range of primary colors, earth tones, black, and white can be enough for learning mixing.
Larger sets are helpful when you want convenience and less time spent mixing custom shades.
For many artists, a 12-color set is enough to start.
A 24- or 36-color set often gives a better balance of variety and usability.
If your work depends on subtle skin tones, landscapes, or highly specific palettes, a larger set may save time.
Matching Oil Pastels to Your Art Style
If your work is expressive and bold, choose softer oil pastels with rich pigment.
If your style is detailed and controlled, choose firmer sticks with clean edges.
Mixed-media artists may prefer a set that works well over watercolor, gouache, or acrylic underpainting.
For sketchbook use, portability and durability may matter more than premium pigment.
For finished illustration or display work, prioritize permanence, color depth, and consistency.
Quick Buying Checklist
- Check pigment intensity and opacity
- Decide how soft or firm you want the sticks
- Review lightfastness and pigment labeling
- Match the set to your paper or surface
- Choose a size that fits your skill level and budget
- Prefer open stock if you plan to use the set often
When learning how to choose oil pastels, focus on how the pastels actually perform in your hands rather than on color count alone.
The best set is the one that matches your technique, supports your surface, and helps you create the effects you want with confidence.
