Should there be a "red letter" version of the New World Translation of the Christian Greek Scriptures?

To me this is rather odd reasoning because there are parts of the Bible that are about Jesus and some about Jehovah, should they be excluded or done in a different color ink? Or what about David or Abraham? Or the parts of Noah or Abednego, see the point? Just because it's a certain topic doesn't mean the ink color should change. Maybe I'm just not getting you're point.
