Fan Casting Red and Black and Evil All Over in Sort by Tropes

Black and red. In western culture, these are the two most sinister colors, as red typically conveys the meaning of blood or anger, and black is that of darkness or death. Being a very visually striking combination, they can also convey a sense of power. Together, they can also give the impression of burning coal or wood, i.e. "fire and destruction". Sticking to these two colors is common for designers who want to create something as sinister as possible.
