coloredlogs: Colored terminal output for Python's logging module

The coloredlogs package enables colored terminal output for Python's logging_ module. The ColoredFormatter_ class inherits from logging.Formatter and uses ANSI escape sequences to render your logging messages in color. It uses only standard colors so it should work on any UNIX terminal. It's currently tested on Python 2.7, 3.5+ and PyPy (2 and 3). On Windows coloredlogs automatically tries to enable native ANSI support (on up-to-date Windows 10 installations) and falls back on using colorama_ (if installed). Here is a screen shot of the demo that is printed when the command coloredlogs --demo is executed:

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Adds colored output to Python's standard logging module using ANSI escape sequences, with automatic fallback support for Windows terminals.

Installation is straightforward with low friction—a pure Python wheel with a single runtime dependency (humanfriendly). However, the package is abandoned as of 1889 days since its last release, meaning no active maintenance or security updates.

MIT license (permissive) places no restrictions on use, modification, or distribution in commercial or private projects.

Usage

pip install coloredlogs

import coloredlogs, logging
logger = logging.getLogger(__name__)
coloredlogs.install(level='DEBUG', logger=logger)
logger.info('colored output')

Requires Python 2.7 or 3.5+; on Windows, native ANSI support requires Windows 10 or the optional colorama package.

Verdict: A stable, well-established logging formatter with no known vulnerabilities and permissive licensing, but abandoned maintenance since June 2021 means no fixes for future Python versions or emerging issues. Suitable for projects that can tolerate a frozen dependency; risky for long-term production use.

Needs verification

Whether the package remains functional with Python 3.9+ given its abandoned status and last release date.
Real-world compatibility with recent Windows 10/11 ANSI terminal support without colorama installed.
Whether humanfriendly dependency itself is actively maintained and compatible with current Python versions.
