Guía práctica de Contrast Checker para sitios web
Aprende un flujo rápido para validar contraste de texto y mejorar legibilidad antes de publicar.
Revisar combinaciones reales de texto y fondo antes de publicar reduce errores de accesibilidad. Aquí tienes una rutina ligera para diseño y QA.
Start with real text combinations
Check actual text/background pairs used in your UI, not only palette swatches.
Prioritize body text, buttons, links, and captions because users depend on them most.
Read ratio and pass/fail together
The ratio shows measurable contrast strength.
WCAG pass/fail tells you whether the combination is acceptable for normal and large text.
Adjust color in small steps
Move one color at a time and retest quickly.
Small shifts in lightness often fix contrast without changing the overall brand feel.
Check states and context
A color pair that passes in one place may fail in hover, disabled, or dark-mode states.
Verify combinations inside real components before final approval.
When this guide helps
- Preparing a new page design.
- Reviewing button and link styles.
- Validating brand colors in UI components.
Use contrast checks early
If you run a quick contrast check during design and QA, accessibility issues are easier to fix and less likely to reach production.
