All three types of paint referenced are water-based. CRAYOLA Portfolio Series acrylic paints are permanent and somewhat lightfast on many different surfaces. They are generally used by adults and older children because of their permanence. Crayola Tempera Paints are generally used by older children. They are an excellent choice for teaching/learning to mix and blend colors. Crayola Washable Paints are typically used by younger children because of their washability. They are neither permanent nor lightfast. For more information about Crayola paints, please visit
