Grey describe neutral, non-committal, cold sophisticated. Grey also signify psychologically gloominess, sadness, ghosts, ashes, cobwebs, and the dust of a haunted house and other scary things.  People in this grey area sometimes have made compromises in their lifestyles. They are practical and calm and don't like to attract attention. And certainly, what I said and wrote after all is not must be the real of me.  I just look something different from  grey. And grey, not always means "trouble inside".
