Local analysis, your colors remain private.
Complete audit of your color palette
Checking one or two color combinations is insufficient. Our analyzer tests ALL possible combinations in your palette and shows you a complete overview of your design system's accessibility. Audit WCAG 2.2 compliance at A, AA and AAA levels: contrast, touch target size, visible focus, text alternatives — a fast accessibility audit for developers and designers. Instantly convert between HEX, RGB, HSL, HSV and CMYK, adjust hue, saturation and lightness with real-time preview and check WCAG AA/AAA contrast for sRGB-compliant accessibility.
Interactive contrast matrix
View all combinations in a color matrix. Immediately identify problematic pairs (in red) and safe combinations (in green). Click to explore details.
Overall accessibility score
Get a 0-100% score indicating the percentage of compliant combinations. Compare your palettes and track accessibility improvement over time.
Import your palette from different sources
Import from CSS (custom properties), Tailwind config, JSON design tokens, .ase files (Adobe), or simply a list of HEX codes. Our tool adapts to your existing workflow.
Automatic improvement recommendations
For each failing combination, the analyzer suggests minimal adjustments. It can propose slightly darkening one color or lightening the other to achieve compliance while preserving visual identity.
Report export for documentation
Generate a professional PDF report for your teams, clients or accessibility audits. Report includes complete matrix, ratios for each pair, recommendations and overall score.
CI/CD workflow integration
Export results as JSON to integrate into your automated test pipelines. Block deployments if accessibility drops below a defined threshold. Ensure continuous compliance.
WCAG 2.2 audit and 2025 legal compliance
The European Accessibility Act (EAA) takes effect in June 2025. Any e-commerce, banking or transport site must comply with WCAG 2.2 AA or face fines. Our analyzer checks contrast ratios to help you achieve compliance.
