David Bowie was asked about his eyes for the “Legends” show on VH-1. He answered by saying that his eyes are actually the same color, but due to getting punched in the eye (as was mentioned in the the staff report) the pupil of one is paralyzed and much bigger than the other. That gives the impression that one eye is darker than the other. And now you know the rest of the story…good day.
Not to pick nits, but this is actually a reference to one of Cecil’s columns, namely: Is it possible to have eyes of two different colors?
Consequently this topic has been moved to the appropriate forum.
What’s this? a long-time member that forgot a link?
