A popular phrase!

"Is the new black" is a common idiomatic expression that means "is the latest trend" or "is the most popular or fashionable thing." It is often used to describe something that is currently in vogue or has become a standard or norm.

The phrase is thought to have originated from the idea that black was once a neutral or basic color, but over time, it became a popular and fashionable color.
