"Jet black" is an expression used to describe when something is really dark black, like the color of the night sky. For example, you could say that someone's hair is jet black if it's very dark and shiny, without any other colors mixed in. You could also use the expression to describe something else that's black, like a car or a dress. It's a vivid way to describe the deep, dark color.
