Dark and Fleshy: The Color of Top Grossing Movies

"I started to think that NC-17 movies perhaps shared a common visual string in their marketing materials — dark and provocative... I started with R and pulled up the top five movies\' posters. Less provocative but very dark. I moved on to PG-13\'s five. Not provocative at all but dark nonetheless. PG\'s five? Much friendlier but, yes, dark. It wasn\'t until I got to the five Gs that I started seeing some bright colors in the movie posters." (Thanks HOW Blog!)
