periodic table of blondness

Another quick note on the latest Monocle.
The "periodic table of blondness" (pages 110-111), about the increasing similarities of TV news anchors (they always tint their hair lighter, never darker), was based on a Slate article written by Jack Shafer, which in turn, was based on Grant McCracken's "Big Hair: A Journey Into The Transformation of Self". Mr. Shafer borrowed the book's different portraits of blondes to rank TV anchors: bombshell blonde (Laurie Dhue of Fox); sunny blonde (Katie Couric of CBS); brassy blonde (Fox's E D Hill); dangerous blonde (CNN's Nancy Grace); society blonde (Fox's Janice Dean); and cool blonde (CNN's resident populist republican, Lou Dobbs). Mr. McCracken seems to be everywhere these days. No wonder, he's excellent.
