Coloring process including：
4 Frosting: A layer of the iced surface.
5 Inner container and external splash: It is showering outwardly of the internal jug, and there is a reasonable hole between the external jug and the external jug. The splash design region is little when seen from the side.
6 Spraying inside the external jug: It is showering on the inward side of the external jug, which looks bigger from an external perspective. The upward plane looks more modest in the region. Also, there is no hole with the inward jug.
