Watercolor vs. Gouache: Exploring the Differences
As a watercolor painter, I’m here to break down the differences between watercolor and gouache. While these two mediums may seem similar, they have distinct characteristics that set them apart from one another.
Gouache vs. Watercolor: Which is right for you?
Choosing between gouache and watercolor ultimately depends on your personal preferences and artistic vision. Both mediums have their own unique strengths and challenges, and it’s up to the artist to decide which one best suits their needs. Watercolor is known for its luminosity and delicacy, while gouache is known for its versatility and ability to be used in a more impasto manner. It’s important to consider the desired effect and the level of control needed when choosing between the two.
Gouache vs Watercolor – Which one is better? In this side by side comparison you can see the differences between those mediums. Visual Mind painted a watercolor and gouache landscape and some watercolour and gouache oranges. You can see how those two mediums just act very differently:
What is watercolor?
Watercolor is a beloved medium among artists for its luminosity and transparency. The pigments are suspended in a water-soluble binder, allowing for the application of thin, delicate layers. This results in a luminous, ethereal quality that is difficult to achieve with other painting mediums.
Advantages of watercolor
One of the benefits of watercolor is its luminosity, which gives paintings a luminous, glowing quality. Additionally, watercolor allows for a great deal of control over the amount of water used, which can create a range of effects, from delicate washes to bold, saturated colors. It’s also relatively easy to clean up, as water can be used to rinse brushes and palettes.
Disadvantages of watercolor
One of the challenges of watercolor is its transparency, which can make it difficult to cover mistakes or create opaque areas. Additionally, watercolor relies on the white of the paper to create highlights, making it necessary to plan ahead and paint around areas that need to remain white.
What is gouache?
Gouache is a more opaque painting medium than watercolor. The pigments are bound in a water-soluble binder, like watercolor, but the ratio of pigment to binder is higher in gouache. This results in a more opaque paint that can be applied in thicker layers.
Advantages of gouache
Gouache has a range of advantages that make it a popular medium among artists. It can be used in a similar manner to watercolor, with thin washes and delicate layering, but it also has the ability to be used in a more impasto manner. This makes it a versatile medium for both fine art and illustration. Additionally, gouache can be reactivated with water, which means that mistakes can be corrected even after the paint has dried.
What is so special about gouache paint?
Gouache paint is a unique medium that offers a range of possibilities for artists. It has a matte finish that is perfect for creating graphic design elements, and it can be used to create a range of effects that are difficult to achieve with watercolor.

Can you use gouache as watercolor?
While gouache and watercolor are different mediums, it is possible to use gouache as watercolor. By diluting the paint with water, it is possible to create delicate washes and layering effects similar to those achieved with watercolor. However, gouache does not have the same luminosity as watercolor, so the effects may be slightly different.
Is gouache easier than watercolor?
The question of whether gouache is easier than watercolor is a subjective one. While gouache does offer some advantages over watercolor, it also has its own set of challenges. For example, gouache can be difficult to mix and can dry quickly, which can make it challenging to work with. Ultimately, the decision of which medium to use depends on the artist’s personal preferences and artistic vision.
Do professional artists use gouache?
Yes, professional artists use gouache. It is a versatile medium that offers a range of possibilities, making it a popular choice among artists of all levels.
Things to consider when choosing between watercolor and gouache
While the article provides a good overview of the differences between watercolor and gouache, there are a few additional details to consider when choosing between gouache and watercolor. Here are some important factors to keep in mind:
- Pigment composition: Watercolor and gouache differ in their pigment composition. Watercolor pigments are generally transparent or semi-transparent, while gouache pigments are more opaque. This can impact how the paint looks on the surface and how light interacts with it.
- Painting surfaces: Both watercolor and gouache can be applied to a variety of surfaces, but there are some surfaces that work better for each medium. For example, watercolor works best on paper, while gouache can be applied to a wider range of surfaces, including paper, board, and canvas. It’s important to choose a surface that is appropriate for the desired effect and to prepare the surface properly before painting.
- Lightfastness: Both watercolor and gouache come in different grades of lightfastness. This refers to how resistant the pigment is to fading over time when exposed to light. It’s important to choose high-quality, lightfast pigments to ensure the longevity of the artwork.
- Mixing with other media: Watercolor and gouache can be mixed with other media, such as acrylic paint or ink. However, it’s important to note that mixing watercolor with acrylic paint can cause the watercolor to become less transparent, while mixing gouache with other media can affect its texture and consistency. When mixing with other media, it’s important to test the combination on a small scale first to see how it behaves.
By keeping these factors in mind, artists can make more informed decisions when choosing a painting medium and ensure that their artwork looks its best and lasts for years to come.
