These are only few screenshots from the movie where light and color, together convey a very special range of moods.
Generally the light is white and contrasts with the background which is very rich in color – usually red. But there is also a strong warm orange light which gives the scene so much intensity. Since nothing is said verbally, the tension , the sadness, the hope, affection are suggested by these means of expression. There is nothing forced , there is common sense in using the colors and the light :their face is not colored in unnatural way, nothing disturbs the viewer, nothing is aggressive, nor too much light since the director uses only a key light. Usually the face of actors are lit from front(butterfly) and some from side.
