In TV production, especially
soap operas, the pages of a script that occur during
dream sequences or coma fantasies are colored
pink. The alternate color of the pages reminds all involved that these events don't actually happen in the storyline of the soap.
On The Simpsons,
Moe's facelift was an example of a "
pink pages" sequence.
On House M.D., House's sex scene with Cuddy was a "
pink pages" sequence.
