blue oscars?

Has anyone ever heard of a true "blue oscar"? I know a person that
says they have them, but I think they are dyed. He has people
defending him saying threw selective breeding they can achieve a blue
oscar much like a blue dempsey or flowerhorn ect. I still dont believe
that because I can not find any articles to support this. One would
think if in fact there has been a break threw with such a popular fish
people would be talking about it.
