What is purple-faced?

Unfortunately, as an AI language model, I don't have enough information or context to determine what you are specifically referring to when you say "purple-faced." It could be a reference to a person who has a purple-colored face due to certain medical conditions or it could be a colloquial expression used to describe somebody who is angry or embarrassed and has turned red in the face. Please provide more information or context so that I can provide a more accurate response.
