## What it is
A reference document and test suite explaining terminal color standards, from 8-color ANSI palettes to 24-bit TrueColor, including detection methods like COLORTERM. It provides shell scripts to verify a terminal's color support.

## Use cases
- check if my terminal supports truecolor
- understand ansi 256-color vs 24-bit color escape sequences
- test terminal emulator color support
- detect COLORTERM support in a shell script
- learn terminal color standards

## When to choose
- you are writing a CLI tool that emits colored output and need to know which color modes to support
- you want ready-made scripts to test a terminal emulator's color capabilities
- you need a canonical reference on ANSI/TrueColor escape sequence behavior

## When to avoid
- you need a library to programmatically render colors in your app rather than documentation
- you are looking for color palette design tools or themes

## Facets

- function: developer-tools, documentation, terminal-ui
- domain: developer-tools, documentation
