Which film was this?

I know it was featured, but I'm not sure which episode it was. There was a young boy, perhaps with a bike, running up to a building. The cinematography was the aspect being discussed, something about the symbolism of the use of red.

For some reason, I thought it was from Days of Heaven but I just recently watched it and it was not that at all! Does anyone have any idea? It's really bugging ,e.
