Visually, Rouge employs a striking dual aesthetic. Scenes set in the couple’s everyday life—the pet shop, their home, interviews—are shot with a natural, slightly grainy texture. In contrast, the swinging sequences are bathed in rich blue or red tones, creating a dreamy, almost psychedelic atmosphere that enhances the eroticism. This deliberate contrast reinforces the film’s central theme: the tension between the ordinary and the extraordinary.
