Logos and uniforms thumb|The 2012 uniforms. Left to right: home, away, Saturday (away with gray pants), Friday (away with gray pants). The Orioles' home uniform is white with the word "Orioles" written across the chest. The road uniform is gray with the word "Baltimore" written across the chest. This style, with noticeable changes in the script, striping and materials, has been worn for much of the team's history, but with a few exceptions: In 1954, 1989–94 (road) and 1995–2003 (home), the scripted word "Orioles" and block letters are rendered in black with orange trim. The 1995–2003 style featured orange numbers in front but black letters in the back. From 1963 to 1965, the home uniforms featured "Orioles" in block lettering instead of the more familiar cursive script style. It was also rendered in black with orange trim. The underline below the word "Orioles" disappeared from 1966 to 1988. Road uniforms bore the team name from 1954 to 1955 and from 1973 to 2008. Extra white trim was added to the road and alternate uniforms from 1995 to 2000. Sleeveless home alternate uniforms were used in the 1968 and 1969 seasons. Player names were added to the uniforms in 1966, but the home uniforms originally featured black block letters. It would not match the road uniform lettering until 1971, which were orange with black trim.
