Harry potter and the order of the phoenix -1

In this scene , the lighting design is layered in terms of color.The background is colored blue and lit by a dull white light.The two characters in the foreground are lit by yellow colored lights, and this makes them stand out of the background. The yellow lamps in the background seems to be the motivation for this lighting , but the intensity is scaled up to give a surrealistic look.This reinforces the theme of the full move, Magic.
