What is color contrast?

According to WebAIM, “contrast is a measure of the difference in perceived ‘luminance’ or brightness between two colors.” Contrast is expressed as a ratio with a range of 1:1 (both colors are the same; for example, white text on a white background) to 21:1 (for example, black text on a white background).

On April 24, 2024, the Department of Justice published a final rule updating the regulations for Title II of the Americans with Disabilities Act (ADA). This rule emphasizes the need for web content and mobile applications provided by state and local governments, including public higher education institutions, to be accessible to people with disabilities.

In case you missed it, last week the Office of Digital Accessibility (ODA) and COLRS shared an accessibility tip on Color contrast in files and Canvas content.

Several aspects need to be considered when we talk about color contrast, including: ratios, text size, images of text, and non-text guidelines.

Join us to learn how to check for successful color contrast and fix issues in PowerPoint and Canvas.
