to be used as their game cap. They also kept the "A" logo with the new colors applied to it, with a solid black cap used as the alternate cap. Arizona's updated color scheme bore a striking resemblance to the Houston Astros' then-current color scheme (brick red, sand and black) that the latter used until 2012, as well as the NHL's Phoenix Coyotes, whose adoption of said colors predate the Diamondbacks by four years. The white home uniform featured "D-Backs" in red with sand and black trim. The road gray uniform featured "Arizona" in red with sand and black trim. Player names were red with black trim while numbers were black with red trim. The alternate red uniform contained "D-Backs" in sand with red and black trim, with player names in sand with black trim and numbers in black with sand trim.

The latter was introduced in 2013 as a tribute to the victims of the Yarnell Hill Fire. On both uniforms, player names were sand with red trim, and numbers in red with sand trim. 2016–present Prior to the 2016 season, the Diamondbacks reincorporated teal into its color scheme while keeping Sedona Red, Sonoran Sand and black.

Arizona also kept the throwback pinstriped sleeveless uniforms from their 2001 championship season for use during Thursday home games.

The team also reverted to a standard grey uniform after wearing a darker shade on the previous set. Two home white uniforms remain in use: the primary Sedona Red and the alternate teal. They would also wear two black uniforms: one with the primary "A" logo on the left chest and the other with "Los D-Backs" trimmed in teal. Three cap designs were also unveiled, all with a black base: the primary "A" cap, the teal-trimmed "snake"
