## What it is
colors.js is a Node.js library that adds ANSI color and style methods to console output, including text colors, background colors, and styles like bold and underline. It supports both a String.prototype extension API and a safe mode that does not modify native prototypes.

## Use cases
- colorize console.log output in node.js
- add colored text to CLI tool output
- print styled terminal messages with bold or underline
- add background colors to terminal text
- print rainbow or themed text for fun CLI output
- auto-detect terminal color support in a node app

## When to choose
- you want a tiny, simple, zero-dependency way to colorize Node.js console output
- you prefer String.prototype chaining like 'hello'.green
- you need a safe mode that avoids extending native prototypes

## When to avoid
- you need actively maintained software with a clear license
- you want advanced features like 256-color or truecolor support and theme ecosystems
- you are building a large CLI where a more modern library like chalk is preferable

- maturity: maintenance
