I was thinking the same thing re: derivative works. Ordinarily a claim could be made if you took a copyrighted work and created derivative material from it (someone sampling your hook in a new song), but what if you start from a public domain work, and add your own changes? It seems your changes only would be copyrighted. But can you copyright obvious colors? If you took B&W, public domain Mickey and had some preschoolers or an AI or something color it in... would this be yours? What Disney should worry about if they plan to defend their colored Mickey is a team of hacktivists creating derivative colored works from the original pd B&W image and claiming copyright on THAT for another 100 years :)
