Check Contrast Free →WebAIM Contrast Checker vs Web Asset Suite
WebAIM's contrast checker is accurate and widely used. Both tools use the same WCAG relative luminance formula so the contrast ratios are identical. The difference is in the additional features Web Asset Suite provides alongside the core contrast check.
Web Asset Suite adds: a live webpage preview showing your colours in a real layout; colourblind simulation for Protanopia, Deuteranopia, and Tritanopia; a palette contrast grid for checking multiple brand colours simultaneously; CSS variable export and Figma design token export; and an Auto-fix button that generates the nearest passing colour to your original.
When to Use WebAIM and When to Use This Tool
Use WebAIM when: you need a quick single-pair contrast check and prefer the simplest possible interface. It is fast and reliable for one-off checks.
Use Web Asset Suite when: you are building a design system and need to check multiple colour pairs at once (palette grid), when you want to show how colours look in a real layout (live preview), or when you need to export results as CSS variables or Figma tokens. After testing contrast, check your typography with the free font pairings generator.
