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.
