Watercolour and pastel pencils are both art mediums that offer unique characteristics and artistic possibilities. While they share the commonality of being pencil-shaped, their distinct properties set them apart.
Watercolour Pencils
Watercolour pencils are essentially coloured pencils that can be blended and manipulated using water.
- How They Work: The pigments in watercolour pencils are bound with a water-soluble binder. When water is applied, the binder dissolves, releasing the pigment to create a wash.
- Characteristics:
- Water-soluble: Allows for blending and washes.
- Vibrant colours: Can be layered for depth and richness.
- Versatile: Suitable for both detailed drawings and loose washes.
Pastel Pencils
Pastel pencils are similar in appearance to coloured pencils, but they contain a higher concentration of pigment and a softer binder.
- How They Work: The soft, powdery pigment in pastel pencils easily adheres to paper, creating a smooth and velvety texture.
- Characteristics:
- Dry medium: No water required.
- Intense colours: Produce rich and vibrant hues.
- Versatile: Suitable for blending, layering, and achieving textural effects.
Key Differences
Here's a table summarizing the key differences between watercolour pencils and pastel pencils:
| Feature | Watercolour Pencils | Pastel Pencils |
|---|---|---|
| Medium | Water-soluble | Dry |
| Pigment Concentration | Lower | Higher |
| Binder | Water-soluble | Softer |
| Blending | With water | With fingers, blending tools, or other pastels |
| Texture | Smooth, can be layered | Rough, powdery, can be blended |
| Water Resistance | Not water-resistant | Water-resistant |
Ultimately, the choice between watercolour pencils and pastel pencils depends on the desired effect and artistic style.
