ContrastCheck

ContrastCheck is a simple color accessibility utility that helps you compare text and background colors.

Enter or select two colors to calculate their contrast ratio and quickly see how readable the combination may be. The app can help you review color choices for websites, apps, documents, graphics, and interface designs.

ContrastCheck is useful for designers, developers, content creators, and anyone working on readable visual layouts.

The app features a clean professional interface, instant color previews, fast contrast calculations, and clear results.

Contrast guidance is provided as a practical design reference and can help you make more informed text and background color choices.
