What is Gouache Paint

Gouache paint is a type of water-based paint that is known for its vibrant and opaque qualities. It is often used in illustration and design work, as well as in fine art. Gouache paint consists of pigment, a binder (usually gum arabic), and water. When dry, gouache paint creates a matte surface and can be reactivated with water for further manipulation.


Gouache paint is a type of opaque watercolor paint that is made with a higher concentration of pigment and a larger amount of binder, resulting in a more vibrant and opaque appearance.


One of the key characteristics of gouache paint is its opacity. Unlike transparent watercolors, which allow the underlying surface to show through, gouache paint provides excellent coverage and can be used effectively on a variety of surfaces, including paper, board, and canvas.

Gouache paint is also known for its ability to create bold and vibrant colors. The high concentration of pigments in gouache paint allows for intense hues and rich color saturation. This makes gouache paint a popular choice for artists who want to create eye-catching and highly expressive artworks.

Another important characteristic of gouache paint is its ability to dry quickly. Unlike oil paints, which can take days or even weeks to fully dry, gouache paint dries within minutes, allowing artists to work more quickly and achieve their desired effects sooner.

Understanding Paint Permanence

When it comes to choosing paint, permanence is an important factor to consider. Paint permanence refers to how well the colors of a painting will endure over time, resisting fading, cracking, or other forms of deterioration.

Lightfastness and Permanence Ratings

To assist artists in understanding the permanence of gouache paint, manufacturers often provide lightfastness and permanence ratings. Lightfastness refers to how resistant a pigment is to fading when exposed to light, while permanence ratings indicate the overall longevity and durability of the paint.

Lightfastness ratings are typically categorized on a scale from I to III, with I being the most lightfast and III being the least. Permanent ratings are often labeled as “excellent,” “good,” “fair,” or “poor,” indicating the paint’s long-term stability and resistance to fading.

When selecting gouache paint, it is advisable to choose colors with high lightfastness ratings (I or II) and excellent permanence to ensure the longevity of your artworks.

Factors That Affect Gouache Paint Permanence

While gouache paint can provide excellent permanence when used correctly, there are several factors that artists should be aware of that can affect its durability over time.

Exposure to Light

One of the most significant factors that can impact the permanence of gouache paint is exposure to light. Ultraviolet (UV) radiation, in particular, can cause pigments to fade or change color over time. Therefore, it is essential to protect gouache paintings from direct sunlight or other sources of intense light.

To minimize the effects of light on gouache paint, it is advisable to frame your artwork using UV-protected glass or acrylic. These materials help to block out harmful UV rays, prolonging the longevity of the painting and preserving the vibrancy of the colors.
