As the Paciello Group’s website states “the Colour Contrast Analyser (CCA) helps you determine the legibility of text and the contrast of visual elements, such as graphical controls and visual indicators.” CCA is free, works on the Mac and PC. It provides you with:

  1. A pass/fail assessment against WCAG 2.0 color contrast success criteria.
  2. A simulation of certain visual conditions including dichromatic color-blindness and cataracts, to demonstrate how your web content appears to people with less than 20/20 vision.
