Ghengis Khan is reported in some sources to have had red hair and blue eyes. Is this accepted to be true? If so, how?

Ghengis Khan is almost universally shown as an East Asian man in contemporary dramatization, with black hair and dark/black eyes. Are there reports of other peoples in that part of Asia having those same features? Is this description considered to be fantastical?

If Ghengis Khan did have these "white" features, would it have been due to admixture with European and Central Asian peoples?

Dan Carlin's Hardcore History audio covers this. It's been some time, so I will only refer to it.
