The current team colors, uniform, and logo date to 1992. The main team colors are red and white, with blue serving as a prominent accent. The team name is written in red with a blue star serving as the dot over the "i"s, and blue piping is often found in Phillies branded apparel and materials. The team's home uniform is white with red pinstripes, lettering and numbering. The road uniform is traditional grey with red lettering/numbering. Both bear a script-lettered "Phillies" logo, with the aforementioned star dotting the "i"s across the chest, and the player name and number on the back. Hats are red with a single stylized "P". The uniforms and logo are very similar to those used during the "Whiz Kids" era from 1950 to 1969.
The Phillies and their National League compadres, the St. Louis Cardinals, are the only teams in Major League baseball to utilize chain stitching in their chest emblem.
In 2008, the Phillies introduced an alternate, cream-colored uniform during home day games in tribute to their 125th anniversary. The uniforms are similar to those worn from 1946 through 1949, featuring red lettering bordered with blue piping and lacking pinstripes. The accompanying cap is blue with a red bill and a red stylized "P." The uniforms were announced on November 29, 2007, when Phillies shortstop Jimmy Rollins, pitcher Cole Hamels, and Hall of Fame pitcher Robin Roberts modeled the new uniforms.
For the 2009 season the Phillies added black, circular "HK" patches to their uniforms over their hearts in honor of broadcaster Harry Kalas, who died April 13, 2009, just before he was to broadcast a Phillies game. From Opening Day through July 26, 2009, the Phillies wore 2008 World Champions patches on the right sleeve of their home uniforms. In 2010, the Phillies added a black patch with a white "36" on the sleeves of their jerseys to honor Roberts, who died on May 6. Roberts' No. 36 had been previously retired by the team. In 2011, the Phillies added a black circular patch with a 'B' in honor of minority owners Alexander and John Buck, who died in late 2010. In 2015, the Phillies added a black circular patch with a white "SLB" in memory of minority owner Sara L. Buck, who died on August 23, 2014.
In 2016, the Phillies added a red alternate uniform to be used for mid-week afternoon games.
The Phillies are one of four teams in Major League Baseball that do not display the name of their city, state, or region on their road jerseys, joining the Los Angeles Angels of Anaheim, St. Louis Cardinals, and the Tampa Bay Rays. The Phillies are the only team that also displays the player's number on one sleeve except on the alternate jersey, in addition to the usual placement on the back of the jersey.
