Gouache

Gouache

Definition

Gouache is a water-based paint that is similar to watercolor but distinguished by its opacity. Unlike watercolor, gouache contains a higher concentration of pigment and often includes inert fillers, such as chalk, which enhance coverage and create a matte, uniform finish. It is favored for its vibrant colors, smooth application, and ability to layer without transparency.

Applications

• Illustration: Used in professional illustration, comics, and animation for its solid color and vibrant finish.
• Fine Art: Employed by artists seeking matte, opaque layers in paintings, often for mixed media works.
• Design and Drafting: Suitable for posters, signage, and graphic design projects that require consistent color blocks.
• Layering: Can be used over watercolor or ink to correct or highlight areas due to its opacity.

Best Practices

• Apply on smooth, absorbent surfaces such as watercolor paper or illustration board for best results.
• Re-wet dried gouache for touch-ups, but avoid excessive water which can dilute the pigment.
• Store in airtight containers or palettes to prevent drying and cracking.
• Layer from dark to light colors carefully, as gouache can lift underlying layers if reactivated too much.
