Blue is the official mascot of the Indianapolis Colts professional American football team of the National Football League. He is an anthropomorphic blue horse who wears a white Colts jersey with a horseshoe on the front. He was first introduced on September 17, 2006 in the Colts' first home regular season game against the Houston Texans at the RCA Dome, in which they won 43-24. Indianapolis's victory over the Texans that day proved to be a sign of good things to come, both for Blue and for the team. That season, the Colts won Super Bowl XLI, defeating the Chicago Bears and winning their first Super Bowl since arriving in Indianapolis (second Super Bowl title overall). Since joining the Colts, Blue has served a valuable good luck charm for the team while also entertaining Colts fans.
Miles - Due to Peyton Manning playing for both the Denver Broncos and Indianapolis Colts, Blue and Miles have a heated relationship. As seen in a 2017 Papa John's commercial where Miles was showing signs of aggregation towards Blue while Manning was attempting to introduce each other, causing Blue to be nervous.
