## What it is
Aurora is a Go library for ANSI terminal colors that supports Printf/Sprintf-style formatting, chaining, 8-bit colors, grayscale, and hyperlinks. It lets developers colorize terminal output with a simple, composable API.

## Use cases
- colorize terminal output in Go
- print colored text with Printf in Go
- add ANSI colors to CLI tool output
- chain bold and color formatting in Go
- enable or disable colors at runtime
- print 8-bit and grayscale terminal colors

## When to choose
- you need ANSI color output in a Go program or CLI
- you want Printf/Sprintf-compatible colorization
- you need chained styles like bold plus color
- you want a dependency-free, permissively licensed color library

## When to avoid
- you need cross-platform color handling on legacy Windows consoles
- you need a full TUI framework rather than just colors
- you need automatic TTY detection built in

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools, terminal-ui, logging
- domain: developer-tools
- platform: go, cross-platform, cli
- tags: ansi-colors, terminal-colors, printf, golang, command-line
