In TV production, especially
soap operas, the pages of a script that occur
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.
