The fur is grey but not in a conventional way. It looks like a dirty white and perhaps it is. However, it would be usual if he let his coat become so dirty. It does happen sometimes to street cats. It is almost as if they give up. It must be hard because cats are fastidiously clean. He is probably a street cat living in Turkey perhaps. He'll be a community cat. They are very common in Turkey.
The black marking are what I call "van-type" meaning after the Turkish Van. This is an upside down V shape marking on the forehead. And the tail is black too.
