Watching films from I was a little kid, I have observed the development of film from my own perspective. One of the things I have found most interesting in the last couple of years is the color scheme of films. At Animex '09 one of the speakers talked about his work on the color design of "Horton hears a who". He had some really interesting things to say, and this lecture sparked my mind. I would never have thought that so much time and effort was spent on the color design in films. From then on I wanted to look into color theory of films, and figure out how people respond to color.
Researching color design for our film I first looked into color theory, but found that it didn't help me much. The reason that it didn't help me is because it was hard to translate all the theory and make use of it in a moving picture. So I started to look into color theory for films where I started to find some interesting things. In almost all feature films I found out that each scene had its own "color mood" that related to each other to create atmosphere/feeling. I found out that there were certain guidelines to follow, and you should think twice about not following them. I learned that for example warm colors convey safety and cool colors suggest danger.
I wanted to use what I learned in the film to create an atmosphere. Each shot should be colored according to feeling that the scene express. The other compositor and I decided what colors to use for each shot so all the scenes would connect and flow trough out the film. I decided to follow the guidelines and use cool colors for the sad scenes and warm colors the happy scenes.
