I am watching the Pan Far episode of Star Trek (TOS) where Spock and Stan wear purple and green sashes and are to fight one another. This reminds me of the Babylon 5 episode where the Drassi are split into two factions; one wearing purple sashes, the other wearing green sashes.

Didn't Buckaroo Banzai also wear a purple sash? Does that mean that the World Crime League wore green? The world may never know.
