The text in our terminal node app is a bit boring at the moment. This lessons introduces the [`chalk`](https://npm.im/chalk) and [`gradient-string`](https://npm.im/gradient-string) modules to bring a bit of color to the application. You could manually use [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code) to style text, but using a helper library like `chalk` or `gradient-string` makes the task much simpler.
