What is purple orks?

As an AI language model, I don't have any credible sources describing purple orks. However, orks are fictional creatures most commonly depicted in fantasy literature, films, and video games. They are usually described as humanoid beings with green skin and brutish features. In some iterations, orks may display a variety of skin colors, including red, yellow, and blue, but purple orks are not commonly seen. It is possible that the concept of purple orks may exist in some limited artistic originality.
