this collection has a mystical theme. it’s inspired by Manichaeism,that was a mystic and Gnostic religion.
they preached an elaborate dualistic cosmology that described the struggle between good and evil, the first represented by the light and the spiritual world and, the second, by the darkness and the material world. they belief that light is imprisoned in material world and in the end it will be free and the winner of this battle.
therefore,the hole collection is black&white represent light&dark.it start with black, mixing white then it goes to total white.
