Orange/Blue Contrast in Movie Posters and How Often It's Surprisingly Used

This article is over two years old, but still holds true today. Something that many people never notice is how many modern movie posters, regardless of the genre, utilize blue and orange as the dominant colors in the poster. A lot of examples are given in the article, everything from actions to comedies to dramas. The reason for this lies in blue and orange being two of the more complimentary colors in the color spectrum, at least to the human eye. This isn't directly related to the lecture at hand, but it's an interesting point of view in how companies sometimes market films in ways so subtle many don't even realize it.
