Gouache is an opaque watercolor paint. It dries quickly and is easy to clean up. The saturated color and matte finish makes it ideal for photographing and printing, or for creating finished work to display. It can be used in combination with watercolor, ink, pencil, water soluble colored pencils, and pastels. Gouache is the painting medium of choice for many commercial artists and illustrators, and is popular for creating plein air studies.
