Primary home uniforms featured black pinstripes with "Astros" in black script letters and numbers in red. The road uniforms sported "Houston" in red script letters and black numbers. Alternate white uniforms without pinstripes featured all letters in brick red with sand trim, initially with the brick red star logo on the left chest before switching to the "Astros" wordmark by 2002. The Astros also wore black alternate home and road uniforms, with "Houston" (road) and "Astros" (home) emblazoned in front, but switched to brick red alternates by 2002. The letters on both uniforms are in sand with brick red trim. Black caps with the updated star in red became the primary cap while a red cap with the sand star was used as an alternate.
