The team has used cardinal red jerseys since Chris O'Brien bought them for the club in 1898. For most of their history, the Cardinals have used the same basic uniform design of white helmets, white pants with red stripes on the sides, and either red or white jerseys.
Starting in 1947, the team had a logo of a cardinal bird perched on the stitches of a football. However, the club did not attach a logo to their helmets until they debuted a cardinal-head logo in 1960, the year the franchise moved from Chicago to St. Louis.
During their 28 years in St. Louis, the Cardinals frequently wore white at home, especially for games vs. theDallas Cowboys, hoping to bring out the "blue jersey jinx" which supposedly follows the Cowboys. The Cardinals wore white at home at least twice in every season between 1964 and 1981, and for every home game in 1964, 1965 and 1978. They wore white for their 1982 and 1983 home games vs. Dallas, but not at all from 1984 through 1987.
The Cardinals moved to Arizona in 1988, and the flag of Arizona was added to the sleeves the following year. In 1990, the team began wearing red pants with their white jerseys, as new coach Joe Bugel wanted to emulate his former employer, the Washington Redskins, who wear burgundy pants with their white jerseys.
In 1994, the Cardinals participated in the NFL's 75th anniversary throwback uniform program. The jerseys were similar to those of the 1920s Chicago Cardinals, with an interlocking "CC" logo and three stripes on each sleeve. The uniform numbers were relocated to the right chest. The pants were khaki to simulate the color and material used in that era. The Cardinals also stripped the logos from their helmets for the two games, at Cleveland (Sept. 18) and home vs. Pittsburgh (Oct. 30).
The Cardinal head on the helmet was repeated on the white jersey from 1988-1995. In 1996, the state flag of Arizona was moved higher on the sleeve after the Cardinal head was eliminated, and black was removed as an accent color, instead replaced with a blue to match the predominant color of the state flag.. In 2002, the Cardinals began to wear all-red and all-white combinations, and continued to do so through 2004, prior to the team's makeover.
In 2005, the team unveiled its first major changes in a century. The cardinal-head logo was updated to be a more aggressive version of its predecessor, making it look meaner. Numerous fans had called the previous version a "parakeet".[2] Black again became an accent color after an eight-year absence, while trim lines were added to the outside shoulders, sleeves, and sides of the jerseys and pants. Both the red and white jerseys have the option of red or white pants.
Hoping to break a six-game losing streak, the Cardinals wore the red pants for the first time on October 29, 2006, in a game at Lambeau Field against the Green Bay Packers. The Packers won 31–14, and the Cards headed into their bye week with a 1–7 mark. Following the bye week, the Cardinals came out in an all-red combination at home against the Dallas Cowboys and lost, 27–10. Arizona did not wear the red pants for the remainder of the season and won four of their last seven games. However, the following season, in 2007, the Cardinals again wore their red pants for their final 3 home games. They wore red pants with white jerseys in games on the road at the Cincinnati Bengals and Seattle Seahawks. They paired red pants with red jerseys, the all-red combination, for home games against the Detroit Lions, San Francisco 49ers, Cleveland Browns, and St. Louis Rams. The red pants were not worn at all in 2008, but they were used in home games vs. Seattle, Minnesota, and St. Louis in 2009. The red pants were paired with the white road jersey for the first time in three years during a 2010 game at Carolina, but the white jersey/red pants combination was not used in 2011.
The Cardinals' first home game in Arizona, in 1988, saw them play in red jerseys. Thereafter, for the next 18 years in Arizona, the Cardinals, like a few other NFL teams in warm climates, wore their white jerseys at home during the first half of the season—forcing opponents to suffer in darker-colored jerseys during Arizona autumns that frequently see temperatures over 100 °F (38 °C). However, this tradition did not continue when the Cardinals moved from Sun Devil Stadium to University of Phoenix Stadium in 2006, as early-season games (and some home games late in the season) were played with the roof closed. With the temperature inside at a comfortable 70°F (21°C), the team opted to wear red jerseys at home full-time. The Cardinals wore white jerseys at home for the first time in University of Phoenix Stadium on August 29, 2008, in a preseason game against the Denver Broncos.
The Cardinals wore white at home for the first time in a regular season game at University of Phoenix Stadium against the Houston Texans on October 11, 2009. In October 2009, the NFL recognized Breast Cancer Awareness Month, and players wore pink-accented items, including gloves, wristbands, and shoes. The team thought the pink accents looked better with white uniforms than with red.[3]
On many occasions, when hosting the Dallas Cowboys, the Cardinals would wear white in order to force the Cowboys to don their "jinxed" blue jerseys. They have not done this since moving into University of Phoenix Stadium, however.
The 2010 season saw the Cardinals debut a new, alternate black jersey. Prior to its introduction, the Cardinals were the only NFL team without an alternate jersey or throwback kit, save for the NFL's 75th anniversary program in 1994.[4]
