# pastel — Bring colors to your terminal.

License: permissive · Maintenance: abandoned · Downloads: 7.5M/mo

## What it is and what it does

Pastel is a lightweight library for adding ANSI color formatting to terminal output. It provides a simple API to colorize strings using predefined styles (green for info, yellow for comment, black-on-cyan for question, white-on-red for error) or custom style definitions. The library automatically detects whether the output is a TTY and disables colors when appropriate, and allows manual color disabling via a configuration call.

The package has no runtime dependencies and installs easily. It is used internally by cleo and similar terminal UI libraries. However, it has been abandoned since September 2020 with no recent maintenance, meaning it will not receive updates for newer Python versions or address any issues that may arise.

Use it for:

- Add colored output to CLI tools and scripts for better readability and user feedback
- Highlight error, warning, and info messages in terminal applications with predefined semantic styles
- Build terminal-based interfaces that gracefully degrade to plain text when output is not a TTY
- Integrate colored logging or status messages into existing command-line tools

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Pastel adds colored text output to terminal applications using predefined or custom styles, with automatic TTY detection and color disabling support.

Yes, if you need simple terminal coloring in a stable, mature project. Pastel is lightweight, has no dependencies, and works reliably for basic use cases. However, do not use it for new projects or active development—it is unmaintained since 2020 and will not receive updates. Consider alternatives that are actively maintained if you need ongoing support or compatibility with future Python versions.

## Install

pip install pastel
uv add pastel
poetry add pastel

## Installing pastel

Before you install: Low install friction with no runtime dependencies. However, the package is abandoned—last release was 2020-09-16 and no commits since then. It remains functional for current Python versions but will not receive updates or security patches.

License in practice: MIT license is permissive; you can use, modify, and distribute pastel freely in commercial and private projects with minimal restrictions.

Quickstart:

pip install pastel

import pastel
print(pastel.colorize('<fg=red;options=bold>This is bold red</>'))

Verify before relying:

- Whether the package works reliably on modern Python versions (3.10+) despite being unmaintained since 2020
- Whether predefined styles (info, comment, question, error) remain the only bundled options or if custom style registration is fully documented
