I don’t have information in the provided search results about a movie where the world turns black and white except for one person. The search results contain information about the film “Green Book,” which is about a pianist and his driver during a 1962 tour, but this is not the movie you’re asking about. The other results discuss a Halloween event and a theme park, which are not relevant to your query.
Based on my knowledge, you may be thinking of one of several films that use this visual concept:
The most famous example is “Pleasantville” from 1998, where two modern teenagers are transported into a black and white 1950s television sitcom. As they introduce change and rebellion into the conservative town, certain elements and people begin to turn to color, representing their emotional awakening and the disruption of the town’s rigid social order. The color gradually spreads as more people embrace change and individuality.
Another possibility is “Schindler’s List” from 1993, which is primarily in black and white but features a girl in a red coat as the only colored element in certain scenes. This creates a haunting visual effect that emphasizes the tragedy of the Holocaust.
You might also be thinking of “The Wizard of Oz” from 1939, which opens in black and white Kansas and transitions to the colorful land of Oz, though this is the opposite of what you described.
If you can provide more details about the movie, such as when it was released, the plot, or any actors involved, I would be better able to identify the specific film you’re looking for.
