## What it is
pastel is a command-line tool written in Rust to generate, analyze, convert, and manipulate colors. It supports many color formats and spaces such as RGB, HSL, CIELAB, CIELCh, and ANSI 8-bit/24-bit representations, with composable subcommands for shell pipelines.

## Use cases
- convert a color from hex to hsl
- generate visually distinct colors for charts
- pick a color from the screen
- name a hex color from css color names
- print colorized text in shell scripts
- mix and lighten colors from the terminal

## When to choose
- you need quick color conversion or manipulation in the terminal
- you want composable color commands in shell pipelines
- you need ANSI color output or readable text/background pairs in scripts

## When to avoid
- you need a GUI color picker or design tool
- you need color management for images or ICC profiles

## Facets
- artifact type: cli-tool
- maturity: stable
- function: cli, developer-tools
- domain: developer-tools, graphics
- platform: cli, windows, rust, cross-platform
