Finally seeing improvement
Gouache is an opaque, water-based paint similar to watercolor, with which it is sometimes paired. It can be painted light over dark and dark over light, it dries quickly, it remains water soluble after dry, and requires no solvents to clean up. Note: Acryl(a) gouache is just acrylic paint formulated to dry with a matte finish. Designers like this because it's easier to scan or photograph. Acryl(a) gouache has different working properties than traditional gouache.
