Apparently, the color bar you see above can be generated as the representation of the "DNA" of any website, (the one above is Side Salad's), using a simple algorithm that derives the colors and location of those colors from the HTML of that site. Whatever the hell that means.
Out of curiosity, I ran a few other sites for comparison:
The New York Times

The National Enquirer

Playboy

Kathie Lee Gifford's Official Site

U.S. Conference of Catholic Bishops

I'm A Dork
