Kishimoto stated that he had decided to make Zetsu half black and half white to "better show his split personality". Naruto series always intrigues me that there is always something related and connected, and Black and White Zetsu fusion resembles Yin Yang symbol (as I have always know which is symbol of black and white forming circular pattern).
