Insufficient contrast is one of the most common and most measurable accessibility issues, with clear, objective standards to check against.
Check Contrast Against an Established Standard
Widely recognized accessibility guidelines define specific minimum contrast ratios for text against its background, giving you an objective bar rather than a subjective judgment call.
Larger Text Has a Slightly More Lenient Standard
Because larger text is inherently easier to distinguish, guidelines typically allow a somewhat lower contrast ratio for large headings than for small body text.
