"His complexion became pale with anger,"

This really stood out to me this time around, for I argued that the one who turned white at the Meryton meeting had done so out of fear and so must be Wickham. It makes complete sense that if Austen associates a white face with anger that it must have been Darcy who was white in Meryton and that Wickham must have been red. With embarrassment? What was the emotion his red face was portraying?
