Besides its obvious merits, The Young Girls of Rochefort is a schoolbook study example for production design students. I can’t remember the last time when the impression provoked by a film was largely due to its colour scheme. Here’s a guy extracting the colour palette for your own usage. 

This film is the ultimate French version of optimism and joie de vivre, one found during Les Trente Glorieuses, and probably never to be touched again.
