* No central database: There's no official record of everyone's favorite color, famous or otherwise.
* Personal preference: Favorite colors are subjective and can change over time.
* Public knowledge: While some celebrities may mention their favorite color in interviews or social media, many don't.
Instead of trying to count, consider these possibilities:
* Red is a popular color: Red is a vibrant and attention-grabbing color, so it's likely that many people, famous or not, enjoy it.
* Different cultures: Color preferences can vary across cultures. Red may be more popular in certain parts of the world.
Ultimately, it's more interesting to consider the reasons why people might choose red as their favorite color, rather than trying to quantify how many people do.
