He moved over to the window: a smallish, frail figure, the meagreness of his body merely emphasized by the blue overalls which were the uniform of the party. His hair was very fair, his face naturally sanguine, his skin roughened by coarse soap and blunt razor blades and the cold of the winter that had just ended. This is from George Orwell's 1984. In this passage, does the word fair mean thin hair or blonde hair? It's pretty confusing. And one more thing, if I'm allowed, can I understand sanguine face as red-colored face(red complexion, probably good blood circulation)? Thanks in advance!
