Description
Instantly check color contrast ratios to ensure your designs meet WCAG accessibility standards. ContrastScore is a fast, accurate, and offline WCAG accessibility checker built right into your browser. Designed with a striking, highly-legible Swiss/Bauhaus architectural design, this tool ensures your text and background color combinations are perfectly readable for users with visual impairments. Key Features: Real-Time Math: Instantly calculates the mathematical contrast ratio between any two colors based on the official WCAG relative luminance formula. AA & AAA Checks: Visually see if your color pairing passes standard AA (4.5:1) compliance or strict AAA (7.0:1) compliance in real time. Live Preview: See exactly how your text will look against your background color directly inside the app. Swiss Design UI: Enjoy a distinct, grid-based, bold interface that prioritizes function and clarity above all else. Zero Permissions Required: ContrastScore operates completely offline in your browser. It does not read your web pages, store your data, or require any invasive permissions. Build a more accessible web with confidence. Keep ContrastScore in your toolbar and check your colors on the fly!
