A quick guide to using the ADA Contrast Checker

Enter the hex codes for the two colors you want to analyze for ADA compliance, or use the manual selector to pick them manually.

Once the colors are added, the checker will instantly show whether the contrast passes or fails ADA standards. You can test compliance for normal and large text, as well as key design elements.

If your chosen colors don’t meet ADA requirements, the tool can also suggest the nearest compliant alternatives.

The importance of ADA compliant color contrast

Using colors that comply with the Americans with Disabilities Act (ADA) helps ensure readability for people with visual impairments, including those who are color-blind or have low vision.

To meet ADA’s minimum accessibility requirements, your site should follow WCAG Level AA standards. For improved accessibility beyond the minimum, WCAG Level AAA provides stricter guidelines.

Here’s how they work:

  • WCAG Level AA: Minimum contrast ratio of 4.5:1 for normal text and a minimum 3:1 ratio for large text and essential design elements.
  • WCAG Level AAA: Minimum 7:1 ratio for normal text and a minimum 4.5:1 ratio for large text.
