The film is not strictly-speaking black and white. As explained on Wikipedia: "The movie was originally filmed in both black-and-white and Thomson-color, an early and untried color film process. In using both formats, Tati feared that Thomson-color might not be practicable, a concern that proved well-founded after the Thomson firm went bankrupt before the film could be processed. Tati then released the black-and-white version (which features occasional short bursts of colour, hand-coloured by Tati directly onto the frames). In 1995, new technology allowed the restoration of the color copy, which was finished and released by Tati's daughter Sophie Tatischeff and cinematographer François Ede."
