From the developer:
Contraste is a simple app for checking the accessibility of text against the Web Content Accessibility Guidelines (WCAG). The application allows you to quickly know if a combination of colors, for a text and a background, passes accessibility thresholds defined by the W3C, and thus is accessible to users with visual impairments.
