The team introduced a gold alternate jersey (worn with the black pants) during a December 15, 2002 game versus the Minnesota Vikings, a 32–31 loss, but have never worn them since then. Because of the metallic gold's bright color, the gold jerseys were considered the "light" jersey in the game, so the Vikings wore their purple home jerseys as the "dark" colored team. One team must wear "dark" and one team must wear "light", this was done because of black & white t.v. broadcasts so viewers could tell the teams apart. The only exception being if both teams are wearing throwback uniforms, such as Thanksgiving Classic games. From 2003 through 2007, the New England Patriots had a "light" jersey (their alternate, a bright metallic silver) that is not white in which the other team would wear their colored, or "dark" jerseys against them since the third jersey rule was implemented in the NFL in 2002.
