There is no clear answer to what color the Astros are wearing today, as it depends on the specific game and the teams uniform schedule. However, there are some general guidelines that can help predict what the team might be wearing. For example, Monday home games are typically Space City uniforms, Fridays are orange, and Sundays and games when Framber pitches are rainbow sides. Additionally, fans were encouraged to wear orange to the American League Division Series game 1 on October 7th. However, on September 11th, the Astros wore Houston Eagles Negro League throwback uniforms in a game against the Royals. Therefore, it is best to check the teams official website or social media pages for the most up-to-date information on the teams uniform for a specific game.
