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
