Hello there

I'm looking to create some sort of illusion in which a pig changes colour in front of the audience. It doesn't have to be all of a sudden, but hopefully while the audience is distracted by something going at the other side of the stage.

At this point I'm thinking about creating a somewhat square cartoonish pig of plexiglass and put a remote operated LED light inside it, but I was hoping someone might have any experince with changing colours before I go and experiment.

Thanks

A drawing or a live animal?
