This article analyzes the colors in movie posters and discovered that orange and blue are used a ton. The article mentions that this trend is seen a lot since "orange/blue just so happens to be the most common set of complementary colors because blue is 'cool' and orange is 'enthusiastic' and 'energetic.'" Being a Cuse fan, I love this. It's right up there with ole Blue eyes saying "orange is the happiest color."
Now, if only the football team could get it's act together like their hoops counterpart.....
