Erreurs fréquentes de contraste couleur à éviter
Repérez les erreurs de contraste les plus courantes en design et en frontend.
Les problèmes de contraste se répètent souvent: tests trop tardifs, un seul état vérifié, et décisions visuelles sans mesure.
Mistake: checking only default state
Hover, focus, disabled, and active states often fail while default passes.
Always test full component state sets.
Mistake: treating brand colors as untouchable
Brand identity can stay intact while adjusting lightness for readability.
Document accessible alternates for text and interactive UI use.
Mistake: testing large text only
Body copy and helper text require stricter contrast thresholds.
Include small text in every accessibility review.
Mistake: skipping real-background testing
A color can pass on white but fail on cards, banners, and gradients.
Validate color pairs in real layouts.
Useful for
- Design QA checklists.
- Frontend accessibility reviews.
- Component library updates.
Prevent mistakes upstream
Catch contrast problems in design tokens and component specs, and you will fix fewer issues later in QA.
