Combining different art mediums can open up a world of creative possibilities. Gouache paint and watercolor paint are both popular choices among artists, but can they be used together? In this article, we will explore the characteristics of gouache and watercolor paints, examine the differences between the two, and discuss how they can be effectively combined to create stunning works of art.

Understanding Gouache Paint

What is Gouache Paint?

gouache paint is a versatile water-based medium that is known for its opaque and vibrant color properties. It is derived from the same pigment as watercolor paint but is combined with a higher concentration of binders and additives, giving it a unique opaque quality. Gouache paint is typically available in tubes, and its consistency can vary from creamy to thick.

Characteristics of Gouache Paint

Gouache paint offers several distinctive characteristics that set it apart from other mediums. First and foremost, gouache is highly opaque, which means that it can effectively cover underlying layers of paint. This opacity allows artists to easily correct mistakes or make changes to their artwork. Additionally, gouache dries quickly, enabling artists to work in layers without waiting for long drying times. Gouache also has a matte finish, which can add a unique texture to artwork.

Understanding Watercolor Paint

What is Watercolor Paint?

Watercolor paint, on the other hand, is a transparent medium that is also water-based. It consists of pigments mixed with a binder, usually gum arabic, which allows the paint to adhere to paper or other surfaces. Watercolor paint comes in pans or tubes and offers a wide range of colors and transparency levels.

Characteristics of Watercolor Paint

Transparency is the hallmark characteristic of watercolor paint. When applied to paper, the colors remain transparent, allowing the white of the paper to shine through. This quality gives watercolor paintings a delicate and ethereal appearance. Watercolor paint also has a longer drying time compared to gouache, allowing artists to create intricate washes and detailed layers.

Differences Between Gouache and Watercolor

Opacity and Transparency

The most significant difference between gouache and watercolor lies in their opacity and transparency. Gouache paint is opaque, while watercolor paint is transparent. This means that when you apply gouache over watercolor, the underlying watercolor layer will not be visible. The opacity of gouache allows for greater control and the ability to correct mistakes easily.

Drying Time

Another difference is the drying time. Gouache generally dries faster than watercolor, allowing artists to work in layers and make adjustments more quickly. On the other hand, watercolor has a longer drying time, which allows for blending and creating subtle gradations of color.

Color Mixing

The process of color mixing also differs between gouache and watercolor. Gouache paint can be mixed on the palette to create new colors, and the resulting mixtures tend to be vibrant and opaque. Watercolor, on the other hand, is often mixed directly on the paper through overlapping washes, creating a more subtle and transparent effect.


Layering is a technique used in both gouache and watercolor painting, but the results vary. In gouache, multiple layers can easily be applied, as the previous layers are covered by subsequent ones due to the opacity of the paint. In watercolor, layers are built up gradually through transparent washes, allowing for subtle variations in color and value.

Benefits of Combining Gouache and Watercolor

Combining gouache and watercolor paints in your artwork can offer numerous benefits. By using both mediums together, you can achieve a harmonious balance between opacity and transparency, creating stunning visual effects. This combination allows for greater control over the artwork, enabling the artist to emphasize certain areas with opaque gouache and create delicate, transparent washes with watercolor.

Step-by-Step Guide to Combining Gouache and Watercolor

To effectively combine gouache and watercolor paints, you will need a few materials and tools. These include gouache paints, watercolor paints, various paintbrushes, watercolor paper or canvas, a palette for mixing colors, water containers, masking tape, and additional tools for creating texture or adding highlights.

Before you begin painting, it is important to prepare your workspace. Set up your easel or table in a well-lit area where you can comfortably work. Organize your materials so that they are easily accessible, and prepare your water containers by filling them with clean water.

When applying gouache and watercolor together, it is helpful to plan your composition in advance. Determine the areas where you want to use gouache for opacity and where you want to incorporate watercolor for transparency. Start by applying a thin layer of gouache as a base, using a larger brush to cover larger areas. Allow the gouache layer to dry before moving on to the watercolor stage.

Using watercolor over gouache allows you to create soft and translucent effects. Apply watercolor washes over the gouache layer, gradually building up the desired colors and values. Take advantage of the watercolor’s blending properties to create smooth transitions between hues. Experiment with different brush techniques, such as wet-on-wet or wet-on-dry, to achieve various effects.

Blending and mixing colors can be achieved by carefully layering gouache and watercolor. By blending wet gouache with wet watercolor, you can achieve unique color combinations and seamless transitions. Adjust the opacity and transparency of the layers as needed to create the desired visual impact.

Tips and Techniques

Using masking tape for crisp edges

When working with gouache and watercolor together, using masking tape can help achieve clean and sharp edges. Apply the tape to the areas where you want to maintain a defined boundary before applying the paint. Once your painting is complete, carefully remove the tape to reveal the crisp edges.

Experimenting with different brush techniques

Different brush techniques can produce varied effects in your artwork. Try experimenting with brushes of different sizes and shapes to create texture or apply washes. Use dry brushing for adding details or stippling for creating interesting textures.

Creating texture with salt or alcohol

To add texture and visual interest to your artwork, you can experiment with applying salt or alcohol to wet gouache or watercolor. Sprinkle a pinch of salt or apply a small amount of alcohol using a brush or spray bottle, and watch as it creates unique patterns and textures as it interacts with the paint.

Creating highlights with white gouache

White gouache can be used to create highlights or add emphasis to certain areas of your painting. Apply thin layers of white gouache using a small brush to areas where light would naturally hit, such as reflections or highlights on objects.

Using gouache for fine details

Gouache paint can also be used for adding fine details to your artwork. With its opaque nature, gouache allows for precise and controlled mark-making. Use a small brush and thin layers of gouache to add intricate details or refine certain areas of your painting.

Finishing and Preserving Your Artwork

Allowing your painting to dry

After completing your artwork, allow it to dry completely before handling or storing to prevent smudging or damage. Gouache generally dries quickly, but watercolor may take longer, especially if multiple layers have been applied.

Fixing any loose or flaky gouache

If you notice any loose or flaky gouache on your painting after it has dried, you can fix it by gently lifting the loose paint with a clean brush or by applying a fixative. Be careful not to disturb the surrounding layers of paint.

Protecting your artwork with varnish

To preserve your artwork and protect it from environmental factors, consider applying a varnish. Varnishing your painting can enhance the colors and provide a protective layer that prevents fading or damage over time. Follow the manufacturer’s instructions for application and drying times.

In conclusion, gouache and watercolor can be successfully combined to create unique and visually captivating artworks. By understanding the characteristics and differences between these two mediums, as well as following the step-by-step guide and tips provided in this article, you can confidently explore the world of combining gouache and watercolor paints in your artistic endeavors. So go ahead, experiment, and let your creativity flow!
