Check WCAG contrast ratios between text and background colors.
Ensure your designs are accessible with the Color Contrast Checker. It calculates the contrast ratio between foreground text and background colors according to WCAG guidelines.
Select a text color and a background color. The tool calculates the ratio and indicates whether it passes AA and AAA accessibility standards for normal and large text.
Accessibility is not just a nice-to-have; it's a requirement. This offline tool helps you quickly validate your color palettes to ensure readability for visually impaired users.
