Another way of manipulating the mood in film I have seen recently is subtle manipulation of tint of picture. As seen in About a Girl by Brian Percival (2001), the image is gradually turning colder throughout the film. By applying blue colour the whole aura of the film is becoming pessimistic and, quite literally, cold. The method is very subtle, I only really noticed it at the very end when the film returned to the full colour for the last scene.
