WCAG Color Contrast Checker
Determine the contrast ratio between foreground and background colors to ensure WCAG 2.1 compliance.
Web accessibility (a11y) is not just a legal requirement but a fundamental aspect of high-quality software engineering. This tool calculates the contrast ratio between two colors, helping developers ensure their UIs meet WCAG 2.1 Level AA and AAA standards. Proper contrast is essential for users with visual impairments and improves readability for all users in various lighting conditions.
Automating contrast checks during the design-to-code handoff prevents costly refactors later in the development cycle. By integrating these checks into the developer workflow, teams can build more inclusive products. This utility provides the mathematical verification needed to prove that color selections satisfy the perceptual luminance requirements defined by W3C standards.
Privacy: Hex codes and RGB values are processed locally. Your design's color palette remains private and is not tracked or stored.
Terms: Results are based on the standard WCAG relative luminance formula. Final accessibility certification should involve comprehensive manual testing.
