<P> The Broncos wore their white jerseys at home throughout the 1971 season, as well as for 1980 home games vs. the San Diego Chargers and Dallas Cowboys, the latter in hopes to bring out the "blue jersey jinx" which has followed the Cowboys for decades (it worked, the Broncos won 41--20). The Broncos wore their white jerseys for 1983 home games vs. the Philadelphia Eagles, Los Angeles Raiders and Cincinnati Bengals, but would not wear white at home again for two decades--see next section . </P> <P> In 1994, in honor of the 75th anniversary season of the NFL, the Broncos wore their 1965 throwback uniforms for two games--a Week 3 home game against the Raiders, as well a road game at the Buffalo Bills the following week . </P> <P> The Broncos radically changed their logo and uniforms in 1997, a design that the team continues to use to this day . The new logos and uniforms were unveiled on February 4, 1997 . Navy blue replaced royal blue on the team's color scheme . The current logo is a profile of a horse's head, with an orange mane and navy blue outlines . The Broncos' popular live animal mascot Thunder was the inspiration to incorporate a horse - head profile as part of the logo on the team's helmets . During a February 4, 1997 press conference introducing the new logo, the team president and the art director for Nike, who were the creators of the new design, described it as "a powerful horse with a fiery eye and mane ." </P> <P> The Broncos began wearing navy blue jerseys, replacing their longtime orange jerseys that had been the team's predominant home jersey color since 1962 . This new uniform design features a new word mark, numbering font and a streak that runs up and down the sides of both the jerseys and the pants . On the navy blue jerseys, the streak is orange, with an orange collar and white numerals trimmed in orange, while on the road white jerseys, the streak is navy blue, with a thin orange accent strip on both sides, a navy collar and navy numerals trimmed in orange . When they debuted, these uniforms were vilified by the press and fans, until the Broncos won their first ever Super Bowl in the new design that same season . The navy blue jerseys served as the team's primary home jersey until the end of the 2011 season--see next section . </P>
