What our client say about us

  • European Accessibility Act

    At the moment, I am working on compliance with the upcoming European Accessibility Act in our company and have looked at various web/app-based solutions. Contrasts is by far the best solution because it can be opened quickly and at any time and I don't have to convert the web developer's colors into gb values. Really great solution!

  • Awesome for previewing / converting colors (web, code)

    Until now, I've used various websites to check color contrasts. However, it's sometimes super cumbersome, and when our developers send me colors (iOS or RGB), I usually have to convert them first :/ What's cool about Contrasts is that I can now skip both steps. Using a shortcut (similar to Spotlight), a search bar opens, automatically understanding color values or programming code. And it displays WCAG compliance correctly. Really great idea!

  • Contrasts: Elevating Web Design Accessibility to New Heights in Compliance with the European Accessibility Act

    Contrasts is more than just a tool for adjusting contrast; it's a key asset for web designers navigating the complex landscape of accessibility compliance, especially concerning the European Accessibility Act. Its user-friendly interface, EAA-specific features, real-time analysis, compatibility, reporting capabilities, and productivity enhancements make it an essential companion for creating web homepages that are not only visually appealing but also inclusive and compliant with European accessibility standards. I highly recommend Contrasts to fellow designers seeking a reliable solution for meeting the requirements of the European Accessibility Act.
