About Colorable
Overview
Colorable is a web-based tool that evaluates color contrast ratios between text and background colors to verify WCAG accessibility compliance. It displays real-time contrast measurements and accessibility ratings (AAA, AA, fail) as you adjust text hue, saturation, and lightness values.
The tool helps designers and developers ensure their color choices meet accessibility standards without relying on external validators. It combines a visual contrast checker with an interactive color picker interface, letting you experiment with different color combinations and immediately see whether they pass accessibility thresholds.
Key Benefits
- Real-time contrast ratio calculation displayed as a numerical score and accessibility rating.
- Separate hue, saturation, and lightness controls for both text and background colors.
- Instant visual feedback showing exactly how text renders against the selected background.
- Free access to WCAG accessibility compliance checking without signup or account creation.
How It Works
Adjust the hue, saturation, and lightness sliders for your text color and background color. The tool immediately calculates the contrast ratio and displays it alongside a WCAG rating (AAA, AA, or fail). Use the Reverse button to swap text and background colors, or click Random to generate new color combinations and explore compliant options.
Use Cases
- Web designers prototyping color palettes need to verify every combination passes WCAG AA or AAA standards before implementation.
- Frontend developers building accessible interfaces use Colorable to validate text-background pairs during development.
- Accessibility auditors test existing color schemes to identify non-compliant combinations that need redesign.
- UI/UX teams establishing brand color guidelines rely on this tool to ensure all approved colors work together accessibly.
