Gouache is an opaque water-based paint that covers evenly and dries quickly to a matte finish. This opacity sets it apart from watercolour: light colours can be painted over dark ones, corrections are easy to make, and flat, clean areas of colour are achievable, making it a medium of choice for illustration, graphic design and bold colour compositions. Designers gouache is formulated for maximum opacity and colour intensity, particularly suited to precision work and reproduction. Acrylic gouache is water-resistant once dry, allowing layers to be built up without risk of reactivation. Washable tempera suits group workshops and younger artists.
