Blue

Commonly used across comedy and improvisation, "blue" describes material that is sexually explicit, crude, or otherwise adult in nature. The term has roots in vaudeville and burlesque traditions, where performers working "blue" pushed boundaries with risque jokes, innuendo, and vulgar subject matter. In improvisation, going blue typically means introducing sexual content, profanity, or shock humor into a scene. While some performers and venues embrace blue material as a legitimate stylistic choice, many improv teachers and troupes discourage it, particularly among newer performers, because it often functions as a shortcut to easy laughs rather than emerging organically from the scene work. The concern is not moral but artistic: blue choices frequently substitute shock value for genuine connection, character development, or heightened game play. Improvisers who default to blue material risk undermining trust with scene partners and audiences alike. That said, experienced performers can deploy blue content purposefully when it serves the scene's truth or comedic logic. The distinction lies between blue material that arises naturally from committed character choices and blue material used as a crutch when a performer feels stuck or wants a guaranteed audience reaction.
