My pigs' names are Rosebud (Rosie for short), Hilda, and Judas (Judie) - I love flowers and named Rosie so, and my husband is a pokemon fan which gave us Hilda! Judas came pre-named but it fits, so maybe that will give you some inspiration!
If they're boys and you like theme names from shows/movies you could name them Daggett and Norbert (The Angry Beavers), Reid and Morgan or Hotch and Rossi (Criminal Minds), Sam and Dean or John and Bobby (Supernatural), Koda and Kenai (Brother Bear), Jaq and Gus or Major and Bruno (Cinderella), Simon, Theodore and/or Alvin (Alvin and the Chipmunks), Finn and Jake (Adventure Time) or the alternative of Fionna and Cake, etc. If you like animal names you could go with things like Grizzly and Kodiak, Al and Gator, Raven and Sparrow, etc. Or Food names like Peanut Butter or just Peanut(s) and Jelly, Brownie and Cookie, Creme and Sugar, etc.
It would help if we knew what type a stuff you like or what kind of theme you are interested in.
I like the name Chewbacca, but I would shorten it to Chewy and for the multicolored one, how about Patches. I have 6 male pigs and their names are Pickles, Remmy, Opie, Scooby, Cotton and Yogi Bear (I call him Yogi for short).
