lolcat

The tool reads input text and transforms it into a rainbow‑colored output displayed on the terminal. It processes each line or stream, applying a gradient of ANSI color codes so that the characters appear in a sequence of hues, creating a visually striking effect for command‑line output.

It is intended for developers or users who want to add colorful emphasis to console messages, logs, or any textual data shown in a terminal. The program can be invoked directly from the command line, making it suitable for inclusion in scripts, pipelines, or interactive sessions where colored output is desired.

Installation is supported on common Unix‑like systems via package managers: on Linux it can be installed with Snap, and on macOS it is available through Homebrew. The software is marked as stable and includes a command‑line interface as its core feature.
