Outputting text in command-line interface (CLI) applications can be enhanced through the use of colored text, which helps distinguish different types of messages, such as errors and successes. This functionality leverages ANSI escape codes, a standard for controlling text properties like color and font styling in terminal emulators. By inserting specific ANSI codes into the output stream, developers can easily format text to stand out; for instance, using code 31 results in red text for errors, while code 32 produces green text for success messages. The implementation involves constructing an abstraction that simplifies color setting and allows for additional features, such as bold text. Furthermore, there is an opportunity to create a color package within the UI framework to streamline and extend color usage, including the addition of background colors and more advanced 256-color support, all of which enriches user experience in CLI applications.
