Oil Pastels Buying Tips: Choose the Right Set for Your Art

The short answer: The best oil pastels for you depend on your skill level, preferred technique, and budget; prioritize softness for blending, pigmentation for vibrancy, and lightfastness for longevity.

1. Understand Softness and Hardness Grades

Oil pastels range from very soft to hard. Soft pastels (like Sennelier or Mungyo) are buttery and blend easily, ideal for layering and smooth transitions. Hard pastels (like Pentel or Crayola) are firmer, hold a point longer, and are better for detailed work or underpainting. Beginners often prefer a medium softness that offers a balance between blending and control. For professional work, many artists choose soft brands for their rich color payoff. Consider what techniques you use most: blending, impasto, or fine lines.

2. Evaluate Pigmentation and Opacity

High quality oil pastels have concentrated pigments that produce vibrant, opaque colors even on dark paper. Student grade pastels often contain more filler, resulting in weaker color and lower opacity. Look for brands that list pigment content or offer high pigmentation ratings. For example, Mungyo Gallery and Caran d’Ache Neopastel are known for strong pigmentation. If you work on toned or black paper, opacity becomes critical to prevent the paper from showing through. Swatching before buying can help, but reading reviews from trusted sources is a reliable alternative.

3. Check Lightfastness Ratings

Lightfastness indicates how resistant the pigment is to fading over time when exposed to light. For archival work or pieces intended for sale, choose pastels with excellent or very good lightfastness (usually rated with stars or ASTM ratings). Many artists grade brands like Sennelier and Holbein provide detailed lightfastness information. Student grade sets often skip this data, meaning colors may fade within a few years. If you create art for long term display, invest in lightfast pastels. For sketchbooks or practice, lower lightfastness may be acceptable.

4. Consider Price vs. Performance Tradeoffs

Oil pastels range from under $20 for a 24 pack of student grade to over $100 for professional sets. More expensive sets typically offer higher pigment load, softer consistency, and better lightfastness. However, you can achieve great results with mid range brands like Mungyo Gallery or Paul Rubens. A common strategy is to buy a small set of a high end brand (like Sennelier) for your most used colors and supplement with a larger set of a mid range brand for less critical shades. Avoid the cheapest sets if you want vibrant, blendable results; they often feel waxy and lack pigment.

5. Match the Set Size and Color Range to Your Needs

Set sizes range from 12 to 120 colors. Beginners often start with 24 or 36 colors to get variety without being overwhelmed. Professionals may prefer larger sets for nuanced palettes, but many experts recommend buying open stock (individual sticks) to customize your selection. Consider the color range: some sets focus on primary colors, others include earth tones or neons. If you paint landscapes, look for sets with greens, browns, and blues. For portraits, flesh tones are important. Check if the set includes a white stick; white is essential for blending and highlights.

Frequently Asked Questions

Can I use oil pastels on canvas? Yes, oil pastels work on canvas, but you should prime it with gesso or use a textured surface to help the pastel adhere. Some artists prefer canvas boards or stretched canvas. For best results, apply a thin layer of pastel and fix it with a spray fixative or varnish.

Are oil pastels toxic? Most reputable brands are non toxic and safe for general use. However, some pigments may contain heavy metals like cadmium. Always check the label, and avoid eating or inhaling dust. Work in a ventilated area if you use fixatives.

How do I blend oil pastels? You can blend using your fingers, a blending stump, or a cloth. For smoother blends, apply a base layer and then overlay another color. Some artists use a drop of baby oil on a cotton swab to blend, but this can break down the binder. Practice on scrap paper to find your preferred method.
