When to use it

  1. Check whether the text and background color combination in your website or app design mockup has enough contrast to be readable, using WCAG standards.

  2. Web accessibility laws in many countries require public-sector and large corporate websites to meet color contrast standards, and this tool lets you instantly verify whether your design passes.

  3. It shows both the standard thresholds for body text (4.5:1 or higher) and large headings (3:1 or higher) plus the stricter AAA thresholds, so it's great for a quick check before an accessibility review.
