the new jerseys did not show drastic differences save for the aforementioned changes to the Seattle Seahawks' uniforms. The Carolina Panthers unveiled an updated logo and word mark in late January 2012, though it has been reported that the actual uniforms will not be altered at the present time. The Denver Broncos switched their primary home jersey color from navy blue to orange. The orange jerseys that served as the team's alternate colored jersey from 2002–2011 became the primary home jersey, while the navy blue jerseys that served as the team's primary home jersey from 1997–2011 switched to the alternate designation. The change was made due to overwhelming popularity with fans, who clamored for the team to return to wearing orange at home, which was the team's predominant home jersey color from 1962–1996. The Houston Texans celebrated 10 years as a franchise by wearing an anniversary patch throughout the season. The Jacksonville Jaguars switched their primary home jersey color from teal to black, beginning with their Week 5 (October 7, 2012) game against the Chicago Bears. The Kansas City Chiefs debuted captains' patches to their uniforms for the first time in the Week 10 (November 12, 2012) game against Pittsburgh. The patches would remain through the rest of the season but were removed in 2013. The Pittsburgh Steelers unveiled a new throwback uniform in April 2012, which was worn in games against the Washington Redskins and the Baltimore Ravens. The uniforms, based on the 1934 Pittsburgh Pirates (the predecessors to the Steelers), feature broad black and Aztec gold horizontal stripes across the jerseys and socks, reminiscent of bumblebees and prison uniforms. The Seattle Seahawks replaced Seahawk blue with College Navy as the color of their primary uniforms. Their new uniforms consist of a navy blue jersey as their primary home jersey, a white jersey as their primary away jersey, and a wolf grey jersey as an alternate. The Seahawks have three pairs of pants: navy blue with action green feather trim, white with navy blue feather trim, and wolf grey with navy blue feather trim. Each pair of pants, as well as the collar of the jerseys, feature 12 feathers, in honor of the fans, who refer to themselves as the '12th Man'. The Seahawks also tweaked their logo, by changing the lower left stripe from light blue to grey. The Washington Redskins wore throwback uniforms to celebrate their 80th
