Minimum Color Contrast Ratio Changed in WCAG 2

December 15, 2008


Topics: Accessibility, News, Web standards.

In the final release of WCAG (Web Content Accessibility Guidelines) 2, the acceptable minimum color contrast ratio was changed from 5:1 to 4.5:1. I’ve updated both my color contrast tests — Color Contrast Comparison Tool and the Color Contrast Spectrum Tool to reflect the change in contrast ratio. What does this change mean? Essentially, this means that the working group decided that color combinations with lower contrast (more similar colors) were acceptable for general use on the web. This is […]

Topics: Accessibility, News, Web standards.

It’s been a long time coming, but as of today the standards of accessibility expressed in the Web Content Accessibility Guidelines are officially updated.

Topics: Accessibility, News.

Quietly released on the Saturday before Christmas, (what, are they trying to hide this news?) Google announced that their latest Toolbar release supports the Windows Accessibility API (Application Programming Interface). This is (obviously) a Windows-specific release, and even further, it’s just an Internet Explorer release. However, it’s definitely a step in the right direction! I was particularly glad to see the comment: Version 5 comes as a part of our ongoing efforts to enhance accessibility in our client-side and web […]
