“In 1991, Disney forced a group of New Zealand parents in a remote country town to remove their amateur renditions of Pluto and Donald Duck from a playground mural; and Barney has been breaking up children's birthday parties across the U.S., claiming that any parent caught dressed in a purple dinosaur suit is violating its trademark. The Lyons Group, which owns the Barney character, "has sent 1,000 letters to shop owners" renting or selling the offending costumes. "They can have a dinosaur costume. It's when it's a purple dinosaur that it's illegal, and it doesn't matter what shade of purple, either," says Susan Elsner Furman, Lyons' spokesperson.”
