I came across an interesting post on Reddit regarding the film Drive's colour palette. I can't find the Reddit post but I did save the link to the Imgur gallery created by user caulkmeat. Check out the gallery he setup with a keen observation of the orange and blue colour palette used throughout the film. This goes beyond colour grading but shows the effort made to weave a visual theme throughout the film. My best guess is that this is all based on the look of traffic at night. It's pretty interesting an makes a great film even better.
