This is extremely common knowledge, and its not exclusive to Transcendence or The Nail.
transcendence and any devil room item will give you black wings instead
Any item that gives flight will also give you black wings if you picked up an item that makes Isaac black. (The Pact, Brimstone, Lord of the Pit, Whore of Babylon, etc.)
