The Panthers have not worn black on black except for the 2012 regular season against Denver -- a game which they lost 36-14 and which Greg Olsen's TD (above) was one of the few good moments -- and a preseason game against Philadelphia this season, which they also lost. So the "back-in-black" look will be looking for its first win.
While jersey colors are decided months in advance -- the home team gets to pick first -- and cannot be changed, pants color is optional and can be changed at the last minute. The Panthers generally wear silver pants with their black jerseys.
No matter whether Panthers win or lose Sunday, they will wear black jerseys and silver pants vs. New Orleans at home Dec.22 (the Saints wore all black while eviscerating the Panthers Sunday night). Panther fans have long clamored to see the all-black look more often, although some of them would rather the team also had a black helmet it could wear with them (the Panthers do not and have no plans to do so).
The bolt of color in the all-black look -- the electric blue socks -- comes courtesy of Steve Smith, who in 2012 got a sneak peek at the black uniforms before they debuted and was allowed to choose the sock color. So blame No.89 if you don't like that part of it.
The Panthers defeated the San Francisco 49ers' current uniform in the finals of the NFL.com contest, getting about 90 percent of the vote in a contest where fans could vote an unlimited number of times (despite the fact the uniform had only been worn once in team history at that time).
