What is the Giver's appearance in the book The Giver?

In The Giver, we are not provided with a great deal of physical description of the Giver.  He wears the same "special" (Lowry 75) clothes as the Elders in the community wear.  We can infer that he has eyes that are not brown, since Jonas sees "pale eyes that mirrored his own" (75). Jonas cannot see color, yet, with the exception of occasional shimmers of red, but paleness suggests eyes that are blue, green, gray, or hazel.  Jonas tells the Giver he can see the Giver is "very old" (75), with wrinkles, "sagging flesh" (75), and dark circles under his eyes. The Giver tells Jonas that he is not as old as he looks, but being the Giver has aged him. And of course, Jonas is twelve, and when we are young, we often tend to think that adults are much older than they actually are.
