A color commentator or expert commentator is a sports commentator who assists the main (play-by-play) commentator, typically by filling in when play is not in progress. The phrase "colour commentator" is primarily used in Canadian English and the phrase "color commentator" is now rarely used in American English as the role is now more commonly known in the USA as "game analyst" or "match analyst". The person may also be referred to as a summariser (outside North America) or analyst (a term used throughout the English-speaking world). The color analyst and main commentator will often exchange comments freely throughout the broadcast, when the main commentator is not describing the action. The color commentator provides expert analysis and background information, such as statistics, strategy, and injury reports on the teams and athletes, and occasionally anecdotes or light humor. Color commentators are often former athletes or coaches of the sport being broadcast. The term color refers to levity and insight provided by a secondary announcer. A sports color commentator customarily works alongside the play-by-play broadcaster. United States and Canada Commentary teams typically feature one professional commentator describing the passage of play, and another, usually a former player or coach, providing supplementary input as the game progresses. Color commentators usually restrict their input to times that the ball or the puck is out of play, or there is no significant action on the field or the court. They usually defer to the main commentator when a shot on goal or another significant event occurs. That sometimes results in them being talked over or cut short by the primary commentator. Former players and managers also appear as pundits and carry out a similar role to that of the co-commentator during the pre-game show before a given contest and the post-game show after it. In American motorsports coverage, there may be as many as two color commentators in the booth for a given broadcast. In the 2010s, sports broadcasters began to increasingly deploy a "rules analyst", who provides opinions and insights on calls made by referees and is typically also a former official. The practice was first popularized in the NFL, with Fox hiring former officials Mike Pereira and Dean Blandino. The practice has since been extended taking to other sports, with officials such as Steve Javie (basketball), Don Koharski (hockey), and Mark Clattenburg (soccer) having taken on similar roles.
