Working Title: Paint Me Black: From YKTTW
St Fan: There seems to be a bit of confusion about the meaning of this trope.
The way I read it, it applies when a character's costume or equipment spontaneously change color and/or appearance to reflect a change in morality/alignment/worldview or to reflect some form of corruption/cleansing.
It is NOT when a character just switch costume to one identical but of a different color.
Hence, the X-Men, Hulk Hogan and Transformers examples may not qualify at all.
Same thing for the recently added Alladin or Star Wars Infinities examples — that's an Evil Costume Switch (or Good Costume Switch) at best.
