Gouache paint is a type of watercolor paint that is opaque and heavily pigmented. It is made by mixing pigment, a binding agent (usually gum arabic), and water. The result is a paint that dries quickly and can be used on a variety of surfaces, including paper, board, and canvas.
Unlike transparent watercolors, gouache can be applied in thick layers without the colors bleeding or blending together. Gouache paints are often used for illustration, design, and other types of artwork where strong colors and precise lines are desired.
Gouache paints can be reactivated with water, so artists can make corrections or blend colors even after the paint has dried. They can also be mixed with other media, such as acrylics or watercolours, to create unique effects.
