Contrast Report

Contrast Report is a command-line accessibility tool designed to audit website color contrast compliance. By analyzing CSS rules and page layouts, it generates detailed reports flagging violations against WCAG AA and AAA standards.

Key Features of Contrast Report

• WCAG Audit Engine: Evaluates text-to-background color combinations against WCAG 2.1 AA and AAA contrast rules.
• CSS Analysis: Inspects style declarations, theme variables, and active states for hidden violations.
• Suggested Fallbacks: Suggests alternative color hex codes that meet compliance standards with minimal visual change.
• JSON & HTML Export: Saves accessibility reports as structured JSON datasets or styled HTML dashboards.

Benefits of Using Contrast Report

• Ensure Digital Inclusion: Create web pages that remain readable and accessible to users with low vision.
• Avoid Legal Risks: Confirm design compliance with accessibility standards before launching pages to production.
• Automate Auditing: Run contrast checks automatically in dev builds to catch violations before manual reviews.
