so yall know that post about how aziraphale wears deuteranopia-friendly colors bc Crowley is a snake and snakes are colorblind? So everyone agrees that Crowley only sees shades of blue and yellow?
Obviously in the show, his hair is red. In the book, his hair is dark. See where I'm going with this?
he has no idea his hair is red.
I suggest that the book's narrator was informed by Crowley himself, and narrator simply didn't question him.
Thoughts on this theory?
