Black
The Witch loved the color black. It wasn't easy to see someone dressed in black at night, and she liked that.
The color added an aura of danger to her, useful if she needed to scare someone—and she often did.
It made her more mysterious.
True, it was depressing, but the Witch was terminally depressed anyway. Sure, the Ozians considered black a wicked color…but the Witch was wicked, after all.
It was also a color of mourning…and the Witch had plenty to mourn.
It was when she wore black that she thought of the loved ones she had lost...
