What do colors represent?

White is the color that symbolizes death and mourning, and Min experiences several situations in which white is also a symbol of danger. When she experiences problems crossing through a Gate aboard the Red Azalea, she notices that the typical colors are replaced by white. The scenes involving many ghosts are also filled with white. Red is another important color, which symbolizes good fortune. When Min examines a place in the Pale Lightning that has been damaged by bad luck, she notes the red tape marking off the area and knows red was chosen to counter the bad luck.
