Comment vérifier le contraste du texte pour l'accessibilité
Utilisez une méthode simple et répétable pour tester le contraste du texte selon WCAG.
Le contraste du texte est un gain rapide pour la qualité UI. Une vérification courte permet d'attraper la plupart des problèmes courants.
Identify text types first
List body text, helper text, button labels, and links.
Smaller text needs stronger contrast than large headings.
Test each pair with a checker
Enter foreground and background colors and read both ratio and WCAG results.
Document combinations that fail so fixes stay organized.
Fix by changing lightness first
Try lightness adjustments before replacing the full hue.
This usually preserves your visual identity while improving readability.
Retest interactive states
Validate default, hover, focus, active, and disabled states.
Accessibility failures often hide in non-default states.
Where to apply this
- Landing page updates.
- Product UI reviews.
- Design handoff QA.
Make contrast part of QA
Treat contrast checks as a standard release step, just like spelling or layout checks.
