Text and images of text have a contrast ratio of at least 4.5:1 (3:1 for large text).
ADA Relevance: Level AA is the standard courts reference for ADA compliance. Failing this criterion creates direct legal exposure for ADA lawsuits.
Low contrast text is difficult or impossible to read for users with low vision, which affects millions of people. This is one of the most common WCAG violations.
Use a contrast checker tool or ADA CodeFix to scan all text elements. Check text on all backgrounds including images, gradients, and colored sections. Large text (18pt+ or 14pt+ bold) needs 3:1.
Adjust text or background colors to meet minimum ratios. Common fixes: darken light gray text, lighten dark text on dark backgrounds, add semi-transparent overlays behind text on images.
These industries commonly fail WCAG 1.4.3 due to the nature of their website content and functionality:
Different platforms have different levels of built-in support for WCAG 1.4.3:
WCAG 1.4.3 requires that text and images of text have a contrast ratio of at least 4.5:1 (3:1 for large text). This is a Level AA criterion under the Perceivable principle, meaning it is required for ADA compliance (courts reference WCAG 2.1 AA).
Use a contrast checker tool or ADA CodeFix to scan all text elements. Check text on all backgrounds including images, gradients, and colored sections. Large text (18pt+ or 14pt+ bold) needs 3:1.
Yes. WCAG 1.4.3 is a Level AA criterion, and courts consistently reference WCAG 2.1 AA as the standard for ADA compliance. Failing to meet this criterion creates legal exposure for ADA lawsuits, which typically settle for $10,000 to $75,000+.
Failing WCAG 1.4.3 Contrast (Minimum) means low contrast text is difficult or impossible to read for users with low vision, which affects millions of people. This is one of the most common WCAG violations. This violation is detectable by automated scanning tools that ADA plaintiff attorneys use to identify lawsuit targets. ADA CodeFix can scan your site for this specific violation and provide AI-generated code fixes.
