Traditional gouache is often more pigmented than a watercolour, containing a high ratio of coloured pigments and a solid white pigment, which grants it an opaque quality. This makes it a great option for illustrators and watercolourists who prefer bold colours. The base is generally made from Gum Arabic (the same base used in traditional watercolour paint). This base allows the paint to be reactivated, so it can be reworked even after it has fully dried.
