Except for minor modifications, the Saints' logo and uniforms have basically remained the same since the club debuted in 1967. The team's logo is a fleur-de-lis (a symbol of the City of New Orleans and of France's Royal Family, which included the House of Bourbon), while its uniform design consists of gold helmets, gold pants, and either black or white jerseys. Minor changes to the uniform stripes and trim have been made throughout the years. The team wore black helmets during the 1969 preseason, but NFL commissioner Pete Rozelle barred the Saints from using the helmets during the regular season, since Mecom did not notify the league office of the change. Black helmets have never been introduced since, not even as an alternate helmet prior to 2013, when the NFL began to require teams to use only one helmet shell per season.
