How to Paint Foliage Using the Acrylic Glazing Technique

How do you paint people standing in front of trees and other foliage?

When it comes to painting foliage in your acrylic portraits or landscapes, one of the best ways to capture depth and realism is through the acrylic glazing technique. In this guide, we’ll explore how to layer colors, create realistic shadows, and bring your foliage to life with step-by-step instructions and tips.

Understanding the Importance of Color in Foliage

One of the critical aspects of painting foliage is choosing the right colors, especially in shadows. You don’t want to use overly intense chromatic greens that can make your painting look flat or artificial. Instead, opt for grayish-green tones for the shadow areas, which add a natural depth and realism to your work.

For example, the foliage in your painting’s shadowed areas can be made more effective by blending raw umber dark, ultramarine blue, and raw sienna. This combination creates a desaturated, natural green that mimics how shadows in nature would appear—subtle yet impactful. The right use of cool colors like ultramarine blue helps define the cooler, darker regions of the foliage.

Tip: Avoid Bright Greens in Shadows

It’s essential to steer away from vibrant, saturated greens in the shadow areas. These should be saved for the sunlit portions of the trees to achieve a dynamic contrast.

Building Layers with the Glazing Technique

Acrylic glazing allows you to work in thin layers, which can be built up over time to create depth in your foliage. For this, you’ll want to mix a small amount of your chosen paint color with a clear matte medium. This mixture creates a translucent glaze that will enable you to see through to the underlying layers, preserving the details of your initial sketch or previous layers.

In the early stages, you will be blocking in the shadow colors, leaving lighter areas open for subsequent layers. Glazing ensures that each layer of paint adds depth without covering the finer details of your painting.

Technique: Thin Your Paint for Glazing

To thin down your paint, mix a small amount of acrylic medium with the color on your palette. This allows you to gradually build up color, controlling its opacity and intensity while preserving the underlying forms.

Focusing on Shapes Rather Than Details

One common mistake when painting foliage is trying to paint each leaf individually. However, it’s more effective to focus on larger shapes and the overall form of the trees and foliage. By looking at your reference photo closely, identify the primary shapes formed by the clusters of leaves rather than individual leaves themselves.

In your first layers, block in the general shapes with darker colors. For example, using a mix of raw umber dark and ultramarine blue can help you establish the darkest shadow areas of the trees. Once these shapes are in place, you can add highlights or refine the edges as you move forward.

Tip: Simplify the Process by Identifying Shapes

Instead of getting caught up in the small details, focus on simplifying the foliage by working with larger shapes and forms. This will help you achieve a cohesive look while maintaining the overall flow and balance of the piece.

Adding Depth with Layers of Darker Colors

After you’ve laid down your initial shapes and shadows, the next step is to add depth by applying darker tones. Mix in ultramarine blue, raw sienna, and a touch of Indian yellow to your palette to create a deep, cool shadow color. As you apply these layers, ensure that your strokes follow the natural form of the foliage to enhance the illusion of volume and depth.

Using a size 14 angled flat brush will give you control over the direction and width of your strokes, helping you define the darkest parts of the trees. For areas where the shadows are most intense, you can use more pressure and apply a slightly thicker layer of the glaze. Remember, each layer adds another dimension to your foliage, so take your time with this process.

Technique: Chisel Your Brush for Precision

By using a flat brush, you can achieve a sharp edge that helps define the boundaries of your dark shapes. This technique is particularly useful for creating crisp shadows that enhance the realism of your foliage.

Layering Highlights and Mid-Tones

Once your shadow areas are well established, it’s time to add mid-tones and highlights. These layers will give your foliage the brightness and vibrancy it needs to stand out. For sunlit areas, a mix of Indian yellow, raw sienna, and a small amount of titanium white will create the perfect highlight color.

Apply these lighter tones sparingly to avoid overpowering the shadowed areas. Use a dry brush technique to add subtle highlights, mimicking how sunlight would naturally catch on the edges of leaves.

Tip: Build Gradual Highlights

Adding highlights should be done in thin, gradual layers to avoid a stark contrast between your light and dark areas. Glazing with lighter colors will help you build up the highlights over time without overwhelming the painting.

Final Touches: Adding Nuances and Details

Once your layers are complete, it’s time to refine the nuances of your foliage. Use a small brush to add any branches or finer details that may be peeking through the leaves. However, be careful not to overdo it—often, less is more when it comes to these final touches.

If you’ve accidentally painted over an area that you intended to leave lighter, don’t worry. Since you’re working with glazes, it’s easy to go back and adjust your values. Simply apply another glaze layer to adjust the tone of the area.

Technique: Use Glazing to Correct Mistakes

If your highlights or shadows are too intense, apply another layer of glaze to either darken or lighten the area subtly without starting over.

Mastering Foliage with Acrylic Glazing

By following these steps, you’ll be able to create realistic and dynamic foliage using the acrylic glazing technique. Remember to build your layers slowly, focus on large shapes instead of tiny details, and use the right colors for shadows and highlights. With practice, your foliage will enhance the depth and realism of your acrylic paintings, bringing your landscapes and portraits to life.
