Web Accessibility and Contrast
Web Content Accessibility Guidelines (WCAG) are a set of recommendations for making web content more accessible, primarily for people with disabilities. A key aspect of this is color contrast. Sufficient contrast between text and its background is crucial for people with visual impairments, but it also improves readability for everyone in various lighting conditions.
This tool calculates the contrast ratio between your chosen text and background colors and checks it against the WCAG 2.1 standards for different levels of conformance (AA and AAA), helping you design more accessible and user-friendly interfaces.
