colorpicker is a command-line utility for X11 environments that allows users to select a color from the screen. It captures the pixel color under the cursor and outputs the color value in various formats (hex, RGB, etc.). This is useful for developers and designers needing to quickly identify and reuse colors found in applications or images. It's a lightweight alternative to opening a full-fledged image editor or dedicated color picking software.

The utility typically utilizes libraries like Xlib to interact with the X server. It simplifies the process of obtaining color information by providing a direct and efficient method to retrieve color values from the desktop environment. The tool is generally scriptable, allowing it to be integrated into automated workflows or custom tools.

The exact implementation details of colorpicker, and available options, can vary based on the specific distribution or version of the utility. It is essential to consult the help output (colorpicker --help) or the manual page (if available) for accurate information.
