Digital Accessibility: Color Contrast
June 09, 2026 UMB Office of Communications and Public Affairs
Poor contrast can make text difficult or impossible to read for students or members of the public with low vision or color blindness, especially on mobile devices or in bright environments.
Digital accessibility begins with awareness and action across the UMB community. New federal regulations that take effect in April 2027 require public universities, including UMB, to ensure that their websites, course content, digital documents, and online tools are accessible to the public and students with disabilities to access our programs, services, and activities. We will be sharing information and tips in “The Elm Weekly.”
Color contrast plays a major role in readability and accessibility across websites, presentations, flyers, and digital communications. Poor contrast can make text difficult or impossible to read for students or members of the public with low vision or color blindness, especially on mobile devices or in bright environments.
To improve accessibility, use dark text on light backgrounds or light text on dark backgrounds, and avoid relying on color alone to communicate meaning. Free contrast checking tools can help verify that digital content meets accessibility standards before materials are shared with students and the public.
Test your content’s color contrast before publishing.
