Acrylic gouache is the perfect paint for educational materials because it allows for quick creation and beautiful finishes, such as "colors don't dissolve when layered, and colors don't get dirty" and "doesn't run even if water is applied after drying." It's a convenient acrylic paint because it doesn't get dirty when layering colors.
