Rob, I'm a little late coming to this conversation. I personally believe good color restoration help bring history alive in a more accurate way to the people who were alive then. Of course, ethically any colorization should be noted with the particular images.
I think the value is especially true of old silent films taken of people candidly moving about. Here's an example of what I'm talking about from a film dated 1900:

With all that said, I do think it's a little odd that every photo in a biography of Wilson would need to be colorized.
