Color Contrast in Microsoft Word: The Basics

Understanding color contrast is vital for creating accessible documents. This refers to the difference in light between font (or foreground) color and its background, making text readable for everyone, including those with visual impairments. A minimum ratio of 4.5:1 is generally recommended.

Follow along using the above video guide for visual examples of the following guidelines.

Tools for Testing Color Contrast

A crucial step in ensuring Section 508 compliance is using the right tools. One such tool is the Color Contrast Analyzer by TPGI, a free resource that helps test and adjust color combinations in documents. The video shows how to use the tool effectively.

Not all colors naturally comply with the recommended contrast ratios, especially when used on standard white backgrounds. Avoid using light colors like yellow and orange on white backgrounds. Test alternative colors or modify shades to achieve compliance. In the video, we tested yellow and brown on a white background, with the following results:

Beyond Automated Checks: Manual Testing

In the end, when it comes to developing accessible Word documents, creators must understand the importance of color contrast, utilize tools for testing and adjusting colors, and manually test documents alongside automated checks.

Automated tools like Microsoft Word’s Accessibility Checker are helpful, but they don’t necessarily catch every issue. For example, in the video, the blue and green text used on a white background was not flagged by Microsoft’s Accessibility Checker, yet they both failed to achieve the 4.5:1 ratio. Therefore, always manually test your document with tools like the Color Contrast Analyzer.
