Gouache [p] (/É¡uËËaeÊ/ ; [É¡uËËÃ¦Ê]), ËÉ¡waÊ also spelled, guache is a type of paint in the category watermedia consisting of, pigment a binding (agent usually gum), arabic and sometimes added inert, material designed to be used in an opaque. Method it also refers to paintings that use this opaque. method
Gouache is a unique painting medium. It is a water-based paint that can be used like watercolor with thin washes, but it is opaque enough to be used like acrylic.ouache can be reactivated when water is added, so each layer reactivates the color underneath a bit. When used as a watercolor, transparent washes can be used. Although, even coverage of pigment is a bit harder to achieve with gouache. I suspect this is due to the larger particles of pigment in gouache.
