Colour can be an extremely useful tool in film making. Certain hues can make us feel different emotions such as loneliness or remind us of love. Directors use colour to help set a tone, mood and feeling for a scene.

Blue is cold, isolated, calm and cerebral
Purple is fantasy, ethereal, mystic and erotic
