“I downloaded ~ 35k thumbnailed-size images (yay wget — “The Social Network” inspired me to not use curl) from a site that has a lot of movie posters online. I then grouped the movie posters by the year in which the movie they promoted was released. For each year, I counted the total number of pixels for each colour in the year. After normalizing and converting to HSL coordinates, I generated the above visualizations.
