Color Palette as Worldbuilding
Limiting the film to a tightly chosen set of colors, or giving each place or state its own set. The colors tell you about the world and its mood without dialogue.
Lost in Translation
Coppola and cinematographer Lance Acord film Tokyo in neon, fluorescent tubes and late-night artificial light. Those colors make the city beautiful and deeply disorienting at the same time. They don't make Tokyo look hostile or exotic. They show a world that makes sense on its own terms but feels foreign, like the feelings the film is about.
Barbie
Barbieland is built in bright toy pink, from the houses to the cars. The sets needed the paint supplier's whole remaining stock of one shade of pink. When Barbie and Ken reach Los Angeles, the pink is gone, and the real world looks plain next to them.
