The purpose of this study was to develop a color analysis protocol for studying use of colors in films. The typical color use in films of romance, comedy, horror, sci-fi, and action genres was evaluated. A custom-made software was used for extracting contrast, saturation, brightness, red, green, yellow and blue values from all sampled frames. We found that among the chosen five film categories, patterns of coloring could be divided into two groups—one comprised romance and comedy, and the other horror, sci-fi, and action. Colors in romance and comedy tend to have higher contrast and brightness and are rich in red and yellow while in horror, sci-fi and action it is the reverse. Sci-fi films usually show the highest average standard deviation of brightness, as well as red, green, yellow, and blue among these five film categories. This indicates that colors of sci-fi films tend to vary greatly as the story progresses.
