My movie I can't remember is a 80s live action comedy or monster movie. All I remember is at the end the group of people who were like monsters were at a house party & the color scheme was bright. I think it was a comedy or satire. Thanks for any help.

All I could come up with when you said monsters and 80s was Little Monsters

It kind of sounds like the end scene to Labyrinth (1986) , but the movie wasn't a comedy.
