Spectral Tune is a web-based utility that evaluates the color palettes used on websites and applications. It is designed for developers, designers, and content managers who need to ensure their visual designs meet accessibility standards and are legible for all users.

WCAG Compliance Analysis: It scans your site's colors against the Web Content Accessibility Guidelines (WCAG), identifying specific contrast ratios that fail requirements.

Readability Scoring: Beyond basic compliance, the tool provides a readability score for text elements, highlighting areas where user experience may be degraded even if technical standards are met. Actionable Recommendations: For each identified issue, it suggests precise color adjustments—such as lightening or darkening specific hues—to resolve problems without a full palette redesign. Batch Page Scanning: You can analyze multiple pages or entire sites in one operation, generating a consolidated report of color issues across your project. Integration Support: The analysis can be integrated into development workflows, allowing for automated checks during the design or build process.
