Query: Puzzled

As someone who hates the commercial aspect of Christmas, I was delighted to read Skipping Christmas, and was actually rooting for the Kranks to get out of town as fast as possible. Just a concern though, and I hope someone can answer this. Why are the Kranks so relieved to find out that their daughter's Peruvian fiance's skin colour is "not dark at all, but actually, two shades lighter than Luther Krank's"?
