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.
Definition
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.
Characteristics
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.
