Buy up a sports team in a league. Change all their attire to pink and purple. Change the name to something awful like the Washington Pansies, despite the team being from Orlando.
Charge fans double for the old style jerseys and memorabilia. When fans complain, put up a kickstarter saying that you'll change all teams back to their original colors IF you get 10 billion on the kickstarter and make up some bullshit that it would take that amount to change everything back.
If they manage to accomplish this, when the colors change back, add another 25% onto the already doubled price of the merchandise.
