The Red Shirt character is a colloquial reference among fans of a 1960s era television science fiction program. In Star Trek’s opening scenes, two or three of the lead characters (often wearing yellow or blue uniforms) would land on a planet, accompanied by one or two characters wearing red uniforms. Within the first ten minutes of the show, generally someone wearing a red uniform died, and her or his demise introduced the central conflict of the episode’s plot. So, at the beginning of the episode, if someone appeared in a red shirt, you knew that this person, no matter how likeable, competent, or regardless of how much this character connected for the moment with the yellow and blue uniformed lead characters (often the stars of the show), this Red Shirt was toast.
