Since the 2016 season, the Denver Broncos have worn their 'Color Rush' uniforms for one game each year.
Every team has its own version of a Color Rush uniform, something that obviously brings out the team's primary colors in a very loud way, but also something that can be considered a throwback for a lot of teams.
At least, that's true for the Denver Broncos, whose Color Rush uniforms are a callback to the 80s and 90s when the team's uniform was a much simpler design than it is today.
The Broncos changed their uniforms in the late 90s and actually won the first Super Bowl in team history the year they switched from the uniforms they wore for the previous couple of decades.
