You create shading paint by mixing a color with your medium to produce darker, semi-transparent layers, which you then gradually build up to achieve the desired depth and tone.
Here's a more detailed breakdown:
Understanding Shading Paint
Shading isn't about using a single "shading paint" right out of the tube. It's about creating a glaze—a thin, transparent or semi-transparent layer of paint that allows the underlying colors to show through. This creates depth, dimension, and realistic shadows.
Steps to Make Shading Paint:
-
Choose Your Base Color: Start with the color you want to shade. For example, if you're shading a red apple, your base color will be red.
-
Select a Shading Color: The choice of shading color depends on the effect you want to achieve. Here are some common options:
- Complementary Color: Using a color opposite your base color on the color wheel (e.g., green for red, orange for blue, purple for yellow) will create a natural, slightly muted shadow.
- Darker Version of the Base Color: Adding a small amount of black or a darker shade of your base color can create a simple shadow. Be careful not to make the shade too harsh.
- Burnt Umber or Raw Sienna: These earth tones are versatile and can be mixed with almost any color to create realistic shadows.
- Ultramarine Blue: Works well for adding depth and cool shadows, particularly to warm colors.
-
Mix Your Colors: In very small increments, add your shading color to your base color. Remember that a little goes a long way. You want to create a subtle shift in tone, not a completely different color. For example, you can start with 10:1 ratio of base color to shading color, and increase the ratio until you are satisfied with the result.
-
Add Your Medium: This is crucial. Your medium will thin the paint and make it more transparent. The type of medium you use depends on the type of paint:
- Oil Paint: Use linseed oil, stand oil, or a glazing medium.
- Acrylic Paint: Use a glazing medium or acrylic retarder (to slow drying) mixed with water.
- Watercolor Paint: Simply add more water.
-
Test Your Glaze: Before applying the shading paint to your artwork, test it on a separate surface. This will allow you to see the color and transparency and make adjustments if needed.
-
Apply in Thin Layers: Apply the shading paint in thin, even layers. Let each layer dry completely before applying the next. This allows you to build up the shadow gradually and maintain control over the final result.
Example: Shading a Blue Object
| Step | Description |
|---|---|
| 1. Base Color | Blue (e.g., Cerulean Blue) |
| 2. Shading Color | Burnt Umber or a slightly darker blue mixed with a touch of purple |
| 3. Mixing | Mix a tiny amount of the shading color into the blue. |
| 4. Medium | Add acrylic glazing medium (if using acrylics) or linseed oil (if oils). |
| 5. Application | Apply thin, even layers to areas needing shadow. |
Tips for Successful Shading
- Less is More: Start with very small amounts of shading color and medium. You can always add more, but it's difficult to take away.
- Layering is Key: Build up the shadows gradually with multiple thin layers.
- Consider the Light Source: Pay attention to the direction of the light source and where the shadows would naturally fall.
- Practice: Experiment with different color combinations and mediums to find what works best for you.
