Why Every Painter Should Incorporate Underpainting into Their Workflow: The Key to Richer, More Complex Artworks

Introduction: Unlocking the Power of Underpainting

In the world of painting, underpainting is a time-tested technique that many artists use to lay a strong foundation for their artwork. By applying a preliminary layer of paint, usually in a monochromatic or neutral tone, the artist is able to establish key elements like value, contrast, and structure before layering on final colors.

Incorporating underpainting into your artistic workflow allows you to build depth, enhance texture, and create more dynamic compositions. It helps you achieve richer, more complex paintings—whether you're a beginner or an experienced artist.

Why Underpainting Is Crucial for Every Artist

Underpainting is not just a preliminary step; it's a core element of the painting process that influences the overall outcome of the artwork. Here's why it’s essential:

1. Establishing Strong Values and Contrast

The key to creating a three-dimensional painting is understanding light and shadow. Underpainting allows you to block in the values (light and dark areas) first, before worrying about color. This ensures that your final piece has contrast, depth, and balance. By using neutral or monochromatic tones, you can focus on value relationships without being distracted by color choices.

• Value Structure: Underpainting serves as a foundation for dark, mid-tone, and light areas, creating a structure that guides the rest of the painting process.

2. Creating Depth and Dimension

Underpainting lays the groundwork for the three-dimensionality of your painting. Once you have a strong tonal base, layering additional colors will feel more grounded. This foundational step helps you avoid flatness in the final piece and gives the painting richness and vibrancy.

• Illusion of Space: As you build up layers of color on top of the underpainting, it will interact with the foundational tones, creating depth that brings your subject to life.

3. Improving Composition and Structure

Creating an underpainting helps you refine the composition and structure of your artwork early in the process. It allows you to map out the major shapes and values without getting bogged down in the details, giving you the chance to adjust proportions and placements before moving forward with the final layers.

• Refined Framework: The underpainting phase allows you to focus on big picture adjustments, ensuring that your composition is strong and balanced.

Types of Underpainting Techniques

There are several types of underpainting techniques, each with a unique effect on the final piece:

1. Grisaille (Monochromatic Underpainting)

Grisaille involves painting exclusively with gray tones. This technique is often used for works that will be painted in monochrome or black-and-white. It helps focus purely on value without the distraction of color.

• Pro Tip: Grisaille is commonly used in classical oil paintings and is an excellent choice for realism and portraiture.

2. Verdaccio (Greenish Underpainting)

A technique popular during the Renaissance, verdaccio involves using a greenish-gray base. This is particularly useful when painting flesh tones for portraits, as it allows the artist to establish a subtle undertone that mimics the appearance of skin.

• Ideal For: Portrait painters looking for a natural and realistic skin tone.

3. Sanguine (Red/Brown Underpainting)

Sanguine involves using earth-toned colors like burnt sienna or umbra for the underpainting layer. This method helps establish warmth in the artwork, making it particularly effective for works with earthy tones or portraiture.

• Warmth and Glow: This underpainting method provides a natural glow, making it a great choice for still life or figure painting.

4. Color-Based Underpainting

Some artists choose to use a colored underpainting, opting for hues like blue, yellow, or orange. This method can influence the mood and atmosphere of the painting, setting the tone for the colors that follow.

• Vibrant Influence: The color of the underpainting subtly shifts the perception of the final colors, leading to more harmonious and vibrant results.

How to Incorporate Underpainting into Your Workflow

Incorporating underpainting into your workflow may seem intimidating at first, but with a simple process, you’ll soon see how this technique elevates your art. Follow these steps to get started:

1. Prepare the Canvas

Before you begin, prepare your canvas by applying a toned ground (a light or neutral color). This helps neutralize the stark whiteness of the canvas and provides a more even starting point for the underpainting.

• Tip: Use acrylic gesso or a light wash of color to tone your canvas.

2. Sketch the Composition

Once your canvas is prepped, lightly sketch out the composition of your piece. Use a pencil or charcoal to outline the major shapes and focal points of your painting.

• Don’t Overwhelm Yourself: Keep the sketch simple—you’re focusing on big shapes, not small details.

3. Block in the Values

Now that you have a basic structure, use a monochromatic palette (grays, browns, or greens) to block in the dark, mid-tone, and light areas of your painting. This is where you can work on creating value relationships and ensure your subject has proper light and shadow.

• Start Light: It’s better to start with lighter tones and darken them as needed, as underpainting layers often dry darker.

4. Refine the Underpainting

Once the initial underpainting is dry, step back and assess the structure of your piece. Is the composition working? Do the light and shadow areas feel balanced? Refine areas as necessary, paying special attention to areas of contrast and depth.

5. Add Final Layers of Color

Once the underpainting is complete and dry, you can begin layering your final colors on top. These color layers will be enhanced by the underpainting, making them appear more vibrant and integrated.

• Build Slowly: Apply thin layers of color and gradually build up intensity, allowing the underpainting to influence your final work.

Conclusion: Elevate Your Art with Underpainting

Underpainting is not just a step—it's a strategy that every artist should incorporate into their workflow. By starting with a strong tonal foundation, you allow yourself to create richer, more complex works of art that feel balanced, dynamic, and alive.

Whether you’re working with oils, acrylics, or watercolors, this technique is invaluable for creating paintings with depth, texture, and professionalism. It helps you focus on the fundamentals—like light, contrast, and composition—before diving into the details.
