All Text Elements Must Have Sufficient Contrast Colors
- May 15, 2026
- Accessibility, Color and Contrast
Quick Reference
Element Code: AC-025
Issue: Text does not meet WCAG contrast requirements
Impact: Text is difficult or impossible to read for users with visual impairments
Fix: Adjust colors to meet minimum contrast ratios
Detection: axe DevTools, WAVE, Lighthouse, contrast checker tools
What Is This Issue?
WCAG requires minimum contrast ratios between text and background colors. Normal text needs 4.5:1, large text needs 3:1. Insufficient contrast makes text hard to read for everyone, especially users with low vision.
Why This Matters for Your Website
Contrast affects all users, not just those with disabilities. Poor contrast reduces readability in various conditions, including bright sunlight and aging eyes.
How to Fix This Issue
- Check current contrast: Use contrast checker tools
- Darken text or lighten background: Increase the difference
- Test across states: Check hover, focus, and visited states too
Tools for Detection
- WebAIM Contrast Checker: Free online contrast testing
- Chrome DevTools: Shows contrast in element inspector
TL;DR (The Simple Version)
Your text colors do not have enough contrast against backgrounds. Use a contrast checker and adjust colors until you meet at least 4.5:1 ratio for normal text.
