## What it is
CSS Colorguard is a PostCSS-based tool that analyzes CSS files and warns when colors are too similar to existing ones, using the CIEDE2000 color-difference algorithm. It is configurable with ignore lists, thresholds, whitelists, and notation checks, and integrates with build systems like gulp, grunt, and broccoli.

## Use cases
- detect duplicate similar colors in css
- lint css color palette consistency
- warn when new css colors are too close to existing ones
- enforce a design system color set in stylesheets
- find equivalent colors written in different notations
- integrate color checks into gulp or grunt build

## When to choose
- you maintain a large CSS codebase and want to prevent palette drift
- you already use PostCSS or a JS build pipeline and want color linting
- you need perceptually accurate color similarity via CIEDE2000

## When to avoid
- you use preprocessors like Sass with variables instead of raw hex values
- you need active development or new features; the project is in maintenance mode
- you need alpha-transparency-aware color comparison
