Errores de contraste de color en accesibilidad que debes evitar

Identifica fallos comunes de contraste que se repiten en diseño y frontend.

Muchos problemas de contraste son previsibles: revisar tarde, validar un solo estado y decidir por apariencia.

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.
