In order to achieve both a film noir and an accessible-while-creepy aesthetic, Leondis and the art director he worked with, Olivier Besson, incorporated a fair amount of mist and smoke. Leondis also went for an art style inspired by the fashion works of Vivienne Westwood, where it takes elements from a variety of time periods; he summarized the setting's look as a mixture of the middle ages, the industrial revolution, and "Pop sixties." The visual's lighting and shading took cues from the works of Rembrandt. Other influences Leondis used on the look included Brassaï's use of black-and-white and Mary Blair's color style. Leondis stated regarding the coloring, "Olivier would use an unrealistic color like pink for the sky if the emotional moment called for it — and somehow still made it feel like our world."
