I think it's largely because the page is white. How do you color someone beige/brown in a black-and-white medium? Specifically black and white, not grayscale.

A question to you: What is it that makes them drawn specifically white, other than eyes? Is it only the fact that they're on a white background, or is there more there that I am missing.

No that explains it. I guess I was assuming they were drawing them in color to begin with and that they were scanned into b&w.
